Hairball Cat Mousse Supplement
Verified Jun 16, 2026
This is a hairball-control mousse supplement for cats that uses AlaskOmega fish oil, psyllium fiber, and soothing plant ingredients to help support the movement of hair through the digestive tract. The formula also includes biotin and zinc, which can contribute to skin and coat health. It’s designed to be a tasty daily add-on to your cat’s regular, complete diet rather than a stand-alone food.
A well-thought-out hairball supplement that combines omega-3–rich fish oil with fiber (psyllium) and demulcent herbs like marshmallow root and slippery elm to support gut motility and help manage hairballs. It’s best suited for otherwise healthy cats who get frequent hairballs and need extra support on top of a balanced diet. As with any supplement, it doesn’t replace a complete cat food and should be used within the recommended amounts, especially in cats with sensitive digestion or existing medical issues.

KibbleLab Review
Strengths
- Uses AlaskOmega fish oil, providing EPA and DHA omega-3 fatty acids that can support skin, coat, and overall wellness.
- Includes psyllium fiber, which can help with stool formation and the passage of hair through the intestines.
- Contains soothing plant ingredients like marshmallow root and slippery elm that may help support the gut lining and bowel comfort.
- Added biotin and zinc can further support healthy skin and coat, which is helpful for cats that groom heavily.
Considerations
- This is a supplement only and does not provide complete and balanced nutrition, so it must be fed alongside a regular cat diet.
- The formula contains fish oil, which can be an issue for cats with fish allergies or sensitivities.
- Fiber and herbal components may cause soft stools or digestive upset in some cats, especially if the full amount is given too quickly, so the gradual increase is important.
- Because it’s a calorie-containing supplement given daily, portions of the main diet may need slight adjustment in cats prone to weight gain.

Top 5 Ingredients Explained
01
Fish Oil
Fish oil is commonly added to pet foods as a concentrated source of healthy fats—primarily the omega‑3 long‑chain fatty acids EPA and DHA—to boost energy density and palatability. EPA and DHA support skin and coat condition, joint and cardiovascular health, and brain development (cats require preformed DHA), but fish oil is calorie‑dense, can oxidize if not properly stabilized, may contain environmental contaminants unless purified, and high doses can cause gastrointestinal upset or affect blood clotting, so product quality and appropriate dosing are important.
02
Psyllium
Psyllium is a soluble, mucilaginous fiber commonly added to pet foods and supplements to bulk and soften stools, promote regular bowel movements in dogs and cats, aid hairball management in cats, and increase satiety for weight control. It swells when hydrated and must be given with adequate water to avoid risk of intestinal blockage, may affect absorption of some medications, and should be introduced gradually under veterinary guidance for proper dosing.
03
Microcrystalline Cellulose
Microcrystalline cellulose is an insoluble, non-digestible fiber commonly used in pet foods as a bulking agent, binder and texture modifier and to prevent caking. For dogs and cats it can help add bulk for weight management and improve stool firmness without adding calories, but it supplies no digestible nutrients or fermentable prebiotics, so high levels can dilute nutrient density and may affect palatability; it is generally regarded as safe when used appropriately.
04
Marshmallow Root
Marshmallow root is an herbal ingredient sometimes included in pet supplements and foods for its mucilage content, which can soothe irritated mucous membranes and support mild gastrointestinal or respiratory comfort rather than serving as a significant source of nutrients for dogs or cats. It may help calm digestive or urinary irritation, but can slow or reduce absorption of oral medications and should be used under veterinary guidance with attention to dosing, quality, and any pregnancy, metabolic, or drug-interaction concerns.
05
Slippery Elm
Slippery elm is used in pet foods and supplements as a natural demulcent and source of soluble fiber to soothe and support gastrointestinal health, commonly included in formulations for digestive upset, diarrhea, constipation, and inflammatory bowel conditions. It can help coat irritated mucous membranes and promote regularity in dogs and cats, but may bind medications and reduce their absorption so administration timing and veterinary guidance are important, and product quality/sourcing should be considered.
