Anti-Diarrhea Liquid Cat Supplement
Verified Jun 10, 2026
This is a kaolin- and pectin-based liquid supplement designed to help firm loose stools and soothe occasional digestive upset in cats. It’s flavorless and meant to be mixed with food, making it easier to give to picky cats. This product is intended as short-term digestive support, not as a complete diet or a replacement for veterinary care if diarrhea persists.
As a diarrhea support supplement, this product uses a well-established combination of kaolin and pectin that can help bind stool and support cats with mild, short-term digestive upset. The formula is simple, flavorless, and free from artificial colors, which can be helpful for sensitive cats and for mixing into food. It’s best suited as a temporary aid alongside appropriate veterinary evaluation, especially if signs last more than a day or two or your cat is very young, elderly, or has other health issues.

At a Glance
KibbleLab Review
Strengths
- Uses kaolin and pectin, a classic combination that can help firm loose stools and support the gut while the underlying issue is addressed.
- Flavorless liquid that can be mixed into food, which is often easier to give to cats than tablets or flavored pastes.
- Contains common food-grade preservatives rather than artificial colors or flavorings, which is reasonable for sensitive animals.
- Clear, weight-based dosing instructions help owners give an appropriate amount for most adult cats and larger kittens.
Considerations
- This is a supplement, not a complete and balanced food, so it should only be used short term and in addition to a regular diet.
- Diarrhea in kittens, senior cats, or cats under 5 pounds can become serious quickly, so veterinary guidance is especially important in those cases.
- The product helps manage symptoms but does not treat underlying causes such as parasites, infections, dietary indiscretions, or chronic intestinal disease, which still need veterinary assessment if diarrhea is frequent, severe, or persistent.

Top 5 Ingredients Explained
01
Kaolin
Kaolin is a naturally occurring clay used in pet foods primarily as an anti-caking agent, binder or flow aid to improve texture and prevent clumping rather than as a nutrient source. It is generally inert and safe in small amounts, but provides no nutritional value, can dilute diet energy/minerals if overused, and should be food-grade to avoid contaminants or interference with medication or nutrient absorption.
02
Calcium Amino Acid Chelate
Calcium amino acid chelate is a mineral supplement used in pet foods to deliver bioavailable calcium bound to amino acids, supporting bone and tooth health, muscle and nerve function, and increased needs during growth, pregnancy and lactation in dogs and cats. It is often better absorbed and gentler on the gut than inorganic calcium salts, but must be formulated at appropriate levels and balanced with phosphorus to avoid developmental skeletal problems in growing animals or metabolic issues from excess calcium.
03
Glycerol
Glycerol (glycerin) is used in pet foods primarily as a humectant and sweetening agent to retain moisture, improve texture and palatability, and serve as a solvent or carrier in wet foods, treats, and liquid supplements. It provides a modest source of metabolizable energy for dogs and cats, but in large amounts can cause gastrointestinal upset and may affect blood glucose, so products intended for diabetic pets or sensitive animals should be used with caution.
04
Lactic Acid
Lactic acid is used in pet food primarily as a natural preservative and pH regulator to inhibit spoilage bacteria and molds, extend shelf life, and sometimes adjust flavor or texture in wet and processed diets. It is not a significant nutritional source for dogs or cats and is generally safe at typical use levels, though high concentrations can irritate the mouth or gastrointestinal tract and may warrant caution in pets with metabolic or GI sensitivities.
05
Magnesium Amino Acid Chelate
Magnesium amino acid chelate is a chelated form of the essential mineral magnesium used in pet foods and supplements to provide a readily absorbed source that supports nerve and muscle function, enzyme reactions, and bone health in dogs and cats. Chelation can improve bioavailability and reduce gastrointestinal upset compared with some inorganic salts, but excessive intake or use in animals with kidney disease or a history of urinary stone issues should be avoided and dosing should follow established nutritional guidelines.
