Pickle threw up almost daily for half a year. Food trials, ultrasounds, prescription diets. Vet started talking about steroids. Tried Biopurr first. Vomiting stopped at week three.

NO MORE 3AM HAIRBALL WAKE-UPS.

Pepper hocked up hairballs 2 to 3 times a week, always at 3am. Three weeks on Biopurr and we're down to maybe once a month. I'm sleeping through the night.

BISCUIT DOESN'T KNOW SHE'S ON A SUPPLEMENT.

Pickiest cat on earth. Biopurr is liquid and tasteless. Two drops on her wet food and she demolishes the bowl. Within a month her digestion was visibly better.

PreyKibble
About 70% waterAbout 10% water
Almost no starchUp to 40% starch
Natural enzymes in every biteCooked so hot the enzymes do not survive

One bowl is no big deal. But it is not one bowl. It is every meal, for years. Over time that can wear the gut down. The good bacteria run low. Food gets harder to break down. And what does not break down can come back up, often looking like it did going in. We call it Kibble Gut.

Results vary. If your cat throws up often, loses weight, or stops eating, see your vet first. Biopurr is daily gut support, not a treatment.

Frequently Asked Questions

Does probiotic supplementation actually work for cats?

Yes. Probiotics are beneficial bacteria that cats need to maintain a healthy gut microbiome, the system that controls digestion, immunity, and even brain chemistry. Studies show that probiotic supplementation supports digestive function, immune response, and gut-brain balance in cats. Many cat owners notice improvements in energy levels, coat quality, and overall vitality within 2 to 4 weeks of consistent daily use. However, probiotics are a nutritional supplement, not a medication. They work by restoring microbiome balance, not treating disease.

My cat has kidney disease (CKD). Can probiotics help?

Cats with CKD are actually at higher risk of gut related decline, especially digestive complications which commonly co-occur with kidney disease. A healthy microbiome is essential for proper nutrient absorption and immune function, and since CKD cats are often on restricted diets, supplementing ensures their gut isn't falling further out of balance. While probiotics aren't a CKD treatment, they're considered an important part of supporting overall health in cats managing kidney disease.

My cat vomits frequently. Could probiotics help?

Probiotics play a direct role in gut lining integrity and reducing GI inflammation, one of the common drivers of chronic vomiting in cats. Many cat owners notice improved digestion and less bile vomiting after consistent supplementation. If your cat vomits regularly, restoring the gut microbiome with probiotics targets the root cause rather than just masking the symptom.

How is this different from the probiotics in cat food?

Commercial cat food processing destroys the majority of naturally occurring beneficial bacteria through high heat manufacturing. Even premium brands can't guarantee adequate bioavailable probiotics after processing, storage, and exposure to air. Biopurr bypasses this problem entirely. Our probiotic strains haven't been heat damaged or degraded, so your cat receives the full potency with every dose. Think of it like fresh vegetables versus canned: both contain nutrients, but one delivers significantly more nutrition per serving.

How often should I give Biopurr?

Just two drops of Biopurr mixed into your cat's daily meal provides the probiotic support they need. Cats on processed diets are especially vulnerable to microbiome disruption, so consistent daily supplementation is key. The liquid formula mixes into anything, wet food, moistened kibble, bone broth, tuna water, or homemade meals, without changing taste or texture. Most cat owners notice improvements in energy levels, coat quality, and overall vitality within 2 to 4 weeks. For best results, give the appropriate dose based on your cat's weight once daily, and even picky eaters will accept it without hesitation.

Is Biopurr safe for cats?

Biopurr was formulated with veterinary nutritionists and feline health experts to ensure that our probiotic supplement is suitable for cats of all sizes and breeds, 12 weeks and older.

What if my cat won't eat it?

Biopurr is a virtually tasteless, odorless liquid that disappears when mixed into any type of food. For extra picky eaters, start with a tiny amount (one drop) for 2 to 3 days, then gradually increase to the full dose. Many customers also find success mixing the drops with a teaspoon of tuna juice or bone broth first, then adding to food. Over 95% of "picky eater" concerns are resolved using these simple techniques.

Can I give too many probiotics? Is it safe every day?

No, you cannot give too many probiotics. Unlike fat soluble vitamins (A, D, E, K) that accumulate in the body, probiotics are naturally regulated by your cat's digestive system, meaning any excess your cat doesn't need is simply passed through. This makes daily supplementation completely safe for long term use.

My cat is on a high quality or raw diet. Does she still need this?

Yes, even premium and raw diets benefit from probiotic supplementation. Here's why: fresh meat and raw food naturally contain some beneficial bacteria, but the moment it's processed, frozen, or exposed to air, those bacteria begin dying off. Raw feeders often assume their cats get enough, but without a diverse range of probiotic strains, the gut microbiome remains incomplete. Unless you're feeding fresh, whole prey animals daily, supplementation ensures your cat maintains consistent microbiome balance. Many raw feeding cat parents use Biopurr as "microbiome insurance" to guarantee their cats never experience gut imbalance, especially important for indoor cats with lower bacterial diversity.

What if my cat already seems healthy? Do I really need to add this?

Prevention is always easier than treatment. Gut microbiome disruption develops slowly and silently. By the time symptoms appear (vomiting, digestive issues, behavioral changes, litter box problems), damage has already occurred. Indoor cats, senior cats, and cats on dry food heavy diets are especially at risk, even if they "seem fine." Think of probiotics like a seatbelt: you don't wait until after the crash. It's microbiome insurance that costs pennies per day but protects against thousands in emergency vet bills.
