When a cat repeatedly brings up hairballs, it is easy to focus on one ingredient and ask whether pumpkin, psyllium, cellulose, or cat grass is the “best” solution. The evidence is more nuanced.
Hairball-focused cat foods generally rely on dietary fiber and overall digestive support rather than one magic ingredient. Different fiber sources behave differently in the gastrointestinal tract, and research in cats suggests that the type and total amount of fiber can matter.
This guide separates what has direct feline research behind it from what is simply a useful ingredient in a broader formula, so cat parents can read a hairball-control food label with more confidence.
Quick Answer: What Ingredients in Cat Food May Help With Hairballs?
🌾 Dietary Fiber
Fiber is the nutritional feature with the strongest overall rationale in hairball-control diets. Certain fiber-rich diets have been studied for their effect on moving swallowed hair through the digestive tract.
🌱 Psyllium Husk
Psyllium is a soluble, gel-forming fiber. A controlled feline study found increased fecal hair excretion in long-haired cats eating higher-fiber diets containing psyllium, although the same effect was not demonstrated in short-haired cats.
⬜ Cellulose
Cellulose is an insoluble fiber commonly used in hairball formulas. Evidence is mixed, which is a useful reminder that the presence of a single fiber ingredient does not predict the performance of an entire diet.
🎃 Pumpkin
Pumpkin can contribute dietary fiber, but direct clinical evidence showing that pumpkin alone prevents feline hairballs is limited. It is better evaluated as part of the complete formula rather than as a stand-alone hairball claim.
🌿 Cat Grass
Cat grass may provide plant material and dietary variety, but direct evidence that cat grass as a cat-food ingredient independently prevents hairballs is limited. Avoid treating it as a proven single-ingredient remedy.
🥣 Complete Nutrition
A hairball formula still needs to function as appropriate everyday nutrition. Fiber should be considered alongside protein, fat, calories, life-stage suitability, and the food's nutritional adequacy.
Why Do Hairballs Form in the First Place?
Cats swallow loose hair during normal grooming. Because hair is largely made from keratin and cannot be digested in the same way as food, most swallowed hair normally travels through the gastrointestinal tract and leaves in the stool.
Some hair can remain in the stomach, become entangled, and form a hairball. Cornell University's Feline Health Center notes that large hairballs can occasionally create more serious gastrointestinal problems, even though occasional hairball regurgitation may occur in otherwise healthy cats.
What a Hairball Diet Is Actually Trying to Do
The nutritional goal is generally not to “dissolve” hair. Instead, hairball-focused diets are formulated to help support the normal movement of swallowed hair through the gastrointestinal tract so more of it can leave with the stool rather than accumulating in the stomach.
1. Hair Is Swallowed
Loose fur is ingested during grooming.
2. Digestion Continues
Food is digested, while the hair itself remains largely indigestible.
3. Fiber Changes the Diet Matrix
Fiber can influence stool bulk, gastrointestinal transit, and the way digestive contents move through the gut.
4. Hair May Pass in Stool
The practical objective is to support normal fecal passage of swallowed hair.
What Does the Research Say About Fiber and Hairballs?
This is where careful wording matters. There is evidence that dietary fiber can affect fecal hair excretion in cats, but results depend on the fiber source, diet composition, coat type, and study design.
Psyllium + Higher Total Dietary Fiber
A controlled study of 21 adult cats compared diets containing different total dietary fiber levels together with psyllium. In long-haired cats, the higher-fiber diets increased fecal hair excretion over the 14-day study period.
However, the researchers did not observe the same effect in the short-haired cats. They also stated that further clinical studies would be needed to determine whether the increased fecal hair excretion translates into a meaningful reduction in hairball-related clinical signs.
Not Every Fiber Source Performs the Same Way
Another feline feeding study compared diets containing different fiber sources, including cellulose, beet pulp, and Miscanthus grass. The results differed by measurement and fiber source, and the study did not show a simple “more fiber always equals fewer hairballs” relationship.
That matters when shopping: a label that lists fiber does not tell you everything about how the finished diet will behave. The source, amount, combination, and overall formulation all matter.
Hairball-Support Ingredients: What Each One Actually Contributes
The table below separates the likely nutritional role of each ingredient from the strength of the hairball-specific evidence. This distinction is important for avoiding exaggerated ingredient claims.
| Ingredient | Primary Role | Hairball Evidence | How to Read It on a Label |
|---|---|---|---|
| Psyllium Husk | Gel-forming soluble fiber that contributes to the fiber profile of a diet. | Direct feline evidence exists as part of higher-total-fiber diets, particularly in long-haired cats. | Look at psyllium as part of the total formula—not as proof that the food will eliminate hairballs by itself. |
| Cellulose | Insoluble fiber that can contribute stool bulk and alter gastrointestinal contents. | Mixed evidence. Some research and veterinary guidance support insoluble fiber approaches, but controlled studies have not produced identical results. | Useful as one component of a fiber strategy. Its position on the ingredient list alone cannot tell you the diet's effectiveness. |
| Pumpkin | Provides plant material and dietary fiber. | Limited direct hairball-specific evidence for pumpkin alone. | A reasonable supporting ingredient, but avoid treating “contains pumpkin” as a clinical hairball guarantee. |
| Cat Grass | Plant-based ingredient that can contribute to the overall fiber and ingredient profile. | Limited direct evidence showing cat grass in a complete food independently reduces hairballs. | Best evaluated alongside the formula's other fiber sources and nutritional profile. |
| Chicory Root | A source associated with fermentable/prebiotic fiber components. | Evidence is stronger for digestive and microbiome-related roles than for direct hairball reduction. | Consider it a digestive-support ingredient rather than a stand-alone hairball solution. |
| Overall Dietary Fiber | The combined soluble and insoluble fiber characteristics of the finished food. | Strongest overall rationale among the nutritional strategies used in hairball-control foods, although results vary among formulations and cats. | Evaluate the complete diet rather than choosing food based on one highlighted ingredient. |
Where Does Pumpkin Fit Into a Hairball Formula?
Pumpkin gets a lot of attention in pet nutrition because it contains plant-based fiber. But from an E-E-A-T standpoint, it is important not to turn that familiarity into a claim the research does not support.
✅ What We Can Say
Pumpkin can contribute dietary fiber and can be included as one component of a digestive-support formula.
⚠️ What We Should Not Claim
There is not strong evidence that pumpkin by itself “cures,” “prevents,” or reliably eliminates feline hairballs.
🔎 Better Buying Question
Instead of asking whether a food contains pumpkin, ask how pumpkin fits with the food's other fiber sources, complete nutrition, and feeding purpose.
What About Psyllium Husk?
Psyllium deserves more attention because it has been included in direct feline hair-excretion research. It forms a gel when exposed to water and contributes soluble fiber characteristics to the diet.
In the controlled study discussed above, long-haired cats eating diets containing psyllium and higher levels of total dietary fiber excreted more hair in their feces. But this should not be simplified into “psyllium always prevents hairballs.” The effect was not demonstrated in the short-haired group, and the researchers specifically called for additional clinical studies.
How to Interpret Psyllium on an Ingredient List
- Positive signal: It shows that the formula includes a recognized fiber source used in feline digestive nutrition.
- Not enough by itself: The amount, total fiber profile, other ingredients, calories, and overall nutritional adequacy still matter.
- Do not compare studies by crude fiber alone: Research may report total dietary fiber, while commercial labels commonly guarantee crude fiber.
Is Cellulose Useful for Hairball Control?
Cellulose is an insoluble fiber and is common in hairball-oriented cat foods. Veterinary nutrition resources describe insoluble fibers as ingredients that can help increase stool bulk and move gastrointestinal contents through the colon.
At the same time, controlled feline research has produced mixed findings for cellulose specifically. That makes cellulose a good example of why ingredient-list marketing should not replace evaluation of the complete food.
Where Cat Grass Fits Into the Picture
Cat grass is especially relevant to Just Try because it already forms part of the brand's broader cat-grass and hairball content ecosystem. But a responsible nutritional explanation needs to separate brand relevance from scientific certainty.
Cat grass can be included as a plant-based ingredient in a cat-food formula, but current evidence is not strong enough to say that cat grass alone is a proven hairball-prevention ingredient.

How These Ingredients Come Together in Just Try Hairball Formula
Just Try Hairball Control Cat Food combines several of the ingredients discussed above in one chicken-and-salmon complete cat-food formula.
🌿 Multiple Fiber Sources
The ingredient list includes cat grass, pumpkin, cellulose, psyllium husk, kale, and chicory root, rather than relying on a single highlighted fiber ingredient.
🥩 40% Crude Protein
Chicken meat, salmon meat, chicken liver, and chicken heart appear at the beginning of the ingredient list, with a guaranteed minimum crude protein level of 40%.
🐟 Complete Formula Context
The recipe also includes salmon oil, taurine, vitamins, minerals, fruits, and vegetables as part of the finished daily food.
The important distinction is that this article does not claim the Just Try formula has been clinically proven to prevent hairballs. Instead, the formula contains multiple fiber-related ingredients that align with nutritional strategies commonly used in hairball-control foods.
How to Read a Hairball Cat Food Label
A front-of-pack phrase such as “hairball control” can tell you the product's intended purpose, but it does not tell you enough about the finished diet. The ingredient list, Guaranteed Analysis, nutritional adequacy statement, calorie content, and feeding directions provide more useful context.
Check the Fiber Strategy
Look beyond a single highlighted ingredient. A hairball-focused food may combine several fiber sources with different physical characteristics, such as psyllium, cellulose, pumpkin, or other plant-derived ingredients.
Read the Guaranteed Analysis
Review crude protein, crude fat, crude fiber, moisture, and any additional guaranteed nutrients rather than judging a food only by its marketing claims.
Find the Nutritional Adequacy Statement
For a food intended as the main diet, confirm the label identifies the appropriate nutritional purpose or life stage rather than assuming every hairball product is a complete everyday food.
Check Calories & Feeding Directions
A functional ingredient does not override total calorie intake. Feeding amount still needs to fit the individual cat's body condition, activity level, and overall diet.
Do Not Judge Hairball Food by Crude Fiber Alone
One of the easiest mistakes is to compare two foods by looking only at the crude-fiber percentage and assuming the larger number must be better for hairballs.
That comparison is too simple. Fiber sources differ in characteristics such as solubility, viscosity, fermentability, and particle structure. Experimental feline diets containing cellulose, beet pulp, psyllium, and other fiber sources have not all produced identical digestive or hair-excretion results.
A Better Way to Compare Two Hairball Foods
Fiber Sources
Which ingredients contribute to the fiber system?
Complete Formula
What are the main protein and fat sources, and is the food intended for your cat's life stage?
Calorie Density
How much energy does the food provide at the recommended feeding amount?
Your Cat
Coat length, grooming behavior, stool quality, appetite, and individual tolerance can all affect the practical result.
Hairball Control Cat Food vs Regular Cat Food
Hairball-control foods are not a completely different category of nutrition. They are still cat foods, but the formulation may place greater emphasis on fiber and digestive characteristics intended to support the passage of swallowed hair.
| What to Compare | Regular Complete Cat Food | Hairball-Focused Cat Food |
|---|---|---|
| Primary Goal | Provide everyday nutrition appropriate to the product's stated life stage and purpose. | Provide everyday nutrition while adding a formulation strategy intended to support normal passage of swallowed hair. |
| Fiber Strategy | Fiber content varies widely according to the formula. | Often places greater emphasis on specific fiber sources or combinations. |
| Ingredient Focus | Depends on the individual recipe and intended nutritional purpose. | May include ingredients such as cellulose, psyllium, beet pulp, pumpkin, or other plant-derived fiber sources. |
| Best Fit | Cats without a specific need for a hairball-oriented formula. | Cats whose owners are looking for a dietary strategy to complement grooming and normal digestive management. |
| What It Cannot Replace | Veterinary evaluation when persistent vomiting or gastrointestinal signs occur. | The same. A “hairball” label should never be used to explain away repeated vomiting or illness. |
What Else Matters Besides Ingredients?
Diet is only one part of hairball management. The amount of hair a cat swallows also matters, which means grooming, shedding, coat length, skin health, and excessive licking can change the picture.
🪮 Regular Grooming
Brushing removes loose fur before the cat can swallow it. This can be especially useful for long-haired cats and during periods of heavier shedding.
💧 Water Intake
Adequate hydration is part of normal gastrointestinal function. Keep fresh water readily available and discuss feeding strategies with your veterinarian if hydration is a concern.
🐱 Grooming Behavior
A sudden increase in licking can mean more swallowed hair. Skin irritation, parasites, stress, or other problems may contribute to excessive grooming.
💩 Stool & Appetite
Changes in stool quality, appetite, body weight, or normal behavior provide important context that cannot be captured by counting hairballs alone.
Frequent Vomiting Should Not Automatically Be Called a Hairball Problem
A cat occasionally bringing up a recognizable hairball is different from repeated vomiting, persistent retching, loss of appetite, lethargy, constipation, abdominal discomfort, or unexplained weight loss.
Hair can occasionally contribute to gastrointestinal obstruction, and underlying gastrointestinal or skin disease can also increase hairball problems. If symptoms are frequent, worsening, or unusual for your cat, veterinary evaluation is more appropriate than repeatedly changing foods or adding fiber on your own.
A Practical Ingredient Checklist Before You Buy
Instead of looking for a single “best” hairball ingredient, use this checklist to evaluate the complete product.
✓ Multiple Fiber Sources
Look at how the formula combines different fiber ingredients rather than relying on one front-label claim.
✓ Clear Protein Sources
Review the first ingredients and the guaranteed crude-protein level in the context of the complete recipe.
✓ Nutritional Purpose
Check the nutritional adequacy statement and make sure the food is appropriate for the intended life stage and feeding purpose.
✓ Feeding Information
Review calorie content and feeding directions, then adjust according to your cat's individual needs with professional guidance when appropriate.
✓ Transition Plan
When changing foods, gradual transitions are generally easier on a cat's digestive routine than abrupt switches.
✓ Realistic Expectations
Hairball food is a nutritional management strategy—not a guarantee that a cat will never produce another hairball.

Frequently Asked Questions
What ingredient in cat food helps with hairballs?
Dietary fiber has the strongest overall nutritional rationale. Research has evaluated several fiber sources, including psyllium and cellulose, but results vary according to the type and amount of fiber, the complete diet, and the cats being studied.
Is psyllium husk good for cat hairballs?
Psyllium has been included in controlled feline research. In one study, long-haired cats eating higher-total-dietary-fiber diets containing psyllium excreted more hair in their feces. The same result was not demonstrated in the short-haired group, so it should not be treated as a universal or stand-alone solution.
Does pumpkin help cats with hairballs?
Pumpkin contributes plant material and dietary fiber, but direct evidence proving that pumpkin alone prevents feline hairballs is limited. It is better considered as one component of an overall food formulation.
Does cat grass help with hairballs?
Cat grass can contribute plant material to a cat's routine, but direct evidence that cat grass alone prevents hairballs is limited. For a deeper discussion, see Does Cat Grass Help With Hairballs?
Is higher crude fiber always better for hairballs?
No. Crude fiber does not describe every characteristic of a food's fiber system, and different fiber sources can behave differently. The overall formula, fiber sources, nutritional adequacy, calorie density, and your cat's individual response are all relevant.
How long does hairball cat food take to work?
There is no universal timeline that applies to every commercial hairball food or every cat. Research protocols vary, and individual factors such as coat length, grooming behavior, diet, and gastrointestinal function can affect outcomes. Follow the product's feeding guidance and discuss persistent symptoms with your veterinarian.
When should I see a veterinarian about hairballs?
Veterinary advice is appropriate when vomiting or retching becomes frequent, your cat stops eating, loses weight, appears lethargic, has difficulty passing stool, seems painful, or shows other changes in normal behavior. Not every episode of vomiting is caused by a hairball.

The Final Takeaway
If you are comparing ingredients for hairball control, fiber deserves the most attention—but not as a single number or a single miracle ingredient.
Psyllium has direct feline research behind its use within higher-fiber diets. Cellulose is widely used as an insoluble fiber source, although research findings vary. Pumpkin and cat grass can contribute to the broader ingredient and fiber profile, but current evidence does not justify treating either one alone as a proven hairball remedy.
The more useful question is therefore not:
“Does this food contain one good hairball ingredient?”
It is:
“How does the complete formula combine fiber, nutrition, feeding suitability, and my cat's individual needs?”
