Works very well for my 8 month old kittens
I’m currently on my second bottle of these probiotics, and they’ve been working really well for my kittens. I give it daily to my two-month-old kittens as part of their routine, especially since they’re on a strictly wet food diet. One of my kittens, Luna, tends to have a sensitive stomach, and this has really helped reduce episodes of diarrhea and keep their digestion more regular. I also like how easy it is to use—you just open the capsule and sprinkle it into their food. It’s completely flavorless, and they eat their meals without any issues, which makes things so much easier. Another big plus for me is the variety of probiotic strains in the formula. It feels like a well-rounded, high-quality supplement, and I feel comfortable giving it to them daily. Overall, it’s been a great addition to their routine, and I plan to keep purchasing it since it’s made a noticeable difference.

100% improvement-it works
Unbelievable! I gave this a chance with my 12 year old cat who is facing diarrhea from IBD. It would be almost daily. About two days into giving him one capsule daily in his wet food the diarrhea was gone. It also resolved the occasional blood and mucus in his stool. He has never had another bout of diarrhea since starting on this. It has been two months now and going good. Definitely recommend.

The runs be gone, tummy saver
I have had few instances where my cat has had an upset stomach where they couldn't hold their bowels and had accidents. Those were not fun times, but having this had truly helped them so much in healing and becoming more regulated. When ever they're having issues, which is rarely now, I give them half on a small amount of wet canned food and then let them eat the rest of the canned food without anymore until later on at night I give them the other half and this is only when they're having diarrhea. The amount will honestly depend on the size of your kitten/cat but it's the same for all that they have to have little amounts at a time implemented into their food for a couple of days in a row and they should be back to their regular bowels, but always check with your veterinarian if you can! If they're feeding you can add it to their formula and my cats haven't had any complaints about the flavor in either the can or formula. Overall I would say definitely worth investing in and having on hand for them! They seem to like it and it does work for them!

Seems to work well
My cats take this with no problems. It seems to have calmed down their guts, and stools are normal.

Chicken the cat approves
Chicken the cat approves. I pour the contents of the capsule on his wet dinner and he eats it up. Seems to have helped him have more regular and formed stools. He gets a capsule a day so the bottle lasts a month.

Something is wrong with the batch I got
I’ve been buying this for many months on subscription. It seems to do its job for the most part. But this current bottle I have I noticed looks different. Normally I open the capsules into my cat’s food and it’s like a white fine powder. But this bottle is more of a brown powder and it’s not as fine textured. It’s a clumpier powder and when I opened the capsule I had to squeeze it to move the powder out and the last bit comes out in one solid chunk. One of my cats threw up and the other had diarrhea. I didn’t change their food or anything. I’m going to throw away this bottle. I will still order this product in hopes that this was just a bad batch. But if the next bottle is the same then I’ll be canceling my subscription.

GREAT! Took about a week to work!
I bought this for my cat, who was having diarrhea/loose stools since he's difficult with taking medicine/pills, i had to add two capsules mixed with his food (one in the morning with his wet food and one in the evening/night). MAKE SURE YOU READ THE INSTRUCTIONS. I was scared he was going to smell the probiotic and not want to eat it, but he had no problems with it! It took about a week for him to develop his firm stools/poop again, so just be patient :).

Healed my IBS kitties tummy.
My cat has IBS. Has had it since he was a kitten. Never had firm stools but about a year ago it turned to pudding. Fed him Chewy brand Tiny Tiger wet food and his poop turned to black tar. Screamed when be pooped. Took him to vet, they couldn’t find anything and gave him Fortiflora SA. Seemed to slowly clear up. Ran out of the vet samples, So I bought this because it was cheaper. And he seemed to clear up. But it when it was time to re-order I thought to get the Fortiflora again (silly me). . But what you get online is just for the flora, it’s not the same as the SA formula you get at the vet.So I got this again. And it worked. Again. His poop has form to it again and he’s not yelping in pain when he goes to the bathroom. He’s even throwing up less. My older geriatric cat, he’s 16, we give it to him too and I think he has a little more pep in his step. I don’t plan on switching from this and I highly recommend it for cats with IBS or geriatric cats whose digestion and absorption may be slowing down a bit due to age. It’s not instantaneous it will take up to two or three weeks to see improvement, but remember you’re replenishing healthy bacteria into an upset tummy. I just break open the capsule and mix it into their wet food. Extremely satisfied.

Regulates my cat's poop frequency
This is easy to feed, it's flavourless so my cat eats it with her food with no issues. Decided to try this because she typically poops between 48-72hr intervals which the vet says is a bit long. After taking this, her intervals have gotten shorter, and her appetite has also become better somehow. I've only started to feed her this once a day on alternate days and have seen such results. Will continue to use it!

Works perfectly!!
I'm so impressed!! My cats like it when I open the capsules and use them as sprinkles on their food. It actually works! My cats still use a litter tray - so it makes a massive difference that their poop literally has no smell at all when I use these. When I stop using them though I notice straight away. Helped when I was changing them from kitten food to adult food which seemed to really cause them an upset. I've used them ever since.

Caused ear infection in my cat.
Made of yeast and it caused a yeast infection in my cats ear. Shame because it did help with my cats IBD symptoms and did stop the diarrhoea. If your cat is susceptible to ear infections - linked to yeast, be cautious.

Cat won't go near these.
Cat won't go near them - will stick to the pro-biotic paste from the vet.

Caused Violent Vomiting
My 11 months old cat has never vomited until I gave her one capsule. Absolute shocking. The vomit came out of the cat with such a force. I hope he won't get watery diarrhoea as well.
