Hairball Support Gel Cat Supplement
Verified May 21, 2026
This is a hairball support gel supplement for cats and kittens over 6 months, using psyllium fiber plus salmon and soybean oils to help hair pass through the digestive tract more easily. The high fat content and added biotin and lecithin also support skin and coat health. It’s meant to be given in small amounts alongside your cat’s regular complete diet, not as a primary food.
This is a thoughtfully formulated hairball gel that combines fiber (psyllium) with lubricating oils to help reduce hairball formation and support coat health. The use of salmon oil is a nice plus for omega fatty acids, and the product avoids petroleum, which some owners prefer not to use. It can be a reasonable option for otherwise healthy cats who tend to get frequent hairballs, when used as directed and alongside a balanced cat food.

At a Glance
KibbleLab Review
Strengths
- Uses psyllium seed husk, a gentle, well-tolerated fiber source, to help hair move through the intestines.
- Contains salmon oil and soybean oil, which provide fats and omega fatty acids that can support skin and coat health.
- Includes biotin and lecithin, nutrients commonly used to support coat quality.
- Free of petroleum bases, artificial flavors, and dyes for cats that may be sensitive to those additives.
Considerations
- This is a calorie-dense, high-fat, sugar-containing gel (corn syrup, malt syrup, molasses), so portions should stay small, especially for overweight or diabetic-prone cats.
- Contains soybean oil, which may not be ideal for cats with known soy sensitivities.
- Not a complete and balanced diet, so it must only be used as a supplement alongside a regular cat food.
- Some cats may be sensitive to higher-fiber products; if you notice softer stools or diarrhea, the amount may need to be reduced.

Top 5 Ingredients Explained
01
Biotin
Biotin (vitamin B7) is a water‑soluble vitamin added to pet foods as a micronutrient to support energy metabolism and healthy skin, coat, and paw pad integrity in dogs and cats. Deficiencies are uncommon with commercial diets but supplementation can help with dermatitis or poor coat quality—biotin is generally safe at recommended levels, though therapeutic or high‑dose use should be done under veterinary guidance and raw egg whites can interfere with biotin absorption.
02
Lecithin
Lecithin is commonly used in pet foods as an emulsifier and texture stabilizer—typically derived from soy, sunflower, or egg—and supplies phospholipids (such as phosphatidylcholine) that help disperse fats and maintain product consistency. In small amounts it contributes choline and supports fat digestion and cell membrane health, but it is not a primary nutrient source; soy-derived lecithin may be a consideration for pets with soy sensitivities and very high intakes can occasionally cause mild gastrointestinal upset.
03
Malt Syrup
Malt syrup, typically derived from malted barley, is used in pet foods as a sweetener, binder and flavor enhancer to improve palatability and texture while providing rapidly digestible carbohydrates. It supplies quick energy but has little protein or micronutrients, is high in sugars and calories (which can contribute to weight gain, dental issues or worsen diabetes), may cause gastrointestinal upset if overused, and contains gluten which could be a concern for animals with rare grain sensitivities.
04
Soybean Oil
Soybean oil is used in pet foods as a concentrated fat source and palatability enhancer, providing energy and omega‑6 fatty acids (primarily linoleic acid) that support skin and coat condition. Because it is calorie‑dense and higher in omega‑6 than omega‑3, formulators balance it with omega‑3 sources to avoid an inflammatory imbalance; highly refined soybean oil is unlikely to trigger soy protein allergies but can oxidize and should be stabilized and stored properly, and it does not supply the arachidonic acid cats require from animal fats.
05
Corn Syrup
Corn syrup is a liquid sweetener and humectant used in some pet foods and treats to add simple-carbohydrate energy, improve palatability, texture and moisture retention. It provides minimal essential nutrients, can contribute to excess calories, dental disease and poor glycemic control, and is of limited benefit for obligate carnivores like cats (which have reduced sensitivity to sweet tastes), so its use should be limited—particularly for overweight pets or animals with diabetes.
