Purina Pro Plan Veterinary Diets FortiFlora Probiotic Cat Supplement is rated 4.8 out of 5 by 398.
Rated 5 out of 5 by from A Much Healthier Kitty Our cat had terrible stomach issues most of his adult life. Repeated visits to the vet, all kinds of different foods, etc. did little. He was terribly thin and would cry in pain. We were able to find a formula that works for him: Forti Flora and a novel protein - Nature's Variety Instinct raw rabbit - it comes frozen in a bag. This combination - a packet a day of the Forti Flora + this protein that he could digest normally - has improved his health substantially. We noticed positive changes in his litter box, thickening of his fur, increased energy, and weight gain. He's just such a happier, healthier cat.

Rated 5 out of 5 by from Cat loves it and it works My Vet sold me some of this after my cat had a bout of severe gastritis. Cat is 12, and has always been chronically constipated. For years I've given her psyllium mixed with wet food, which required making sure she ate it before it thickened up. When I started FortiFlora I stopped all other meds, and noticed that she was pooping normally. I'm writing this because I read many posts mentioning the product helped with the runs....well, it helps with constipation too! And the cat loves it!

Rated 5 out of 5 by from Great for all kinds of reasons! This product is great on so many levels. My current foster cat has severe skin allergies, no teeth and is a picky eater. Bad combo. Getting him to eat is a struggle and finding a food that helps his allergies hasn't happened yet. However I started adding this to his food and he LOVES the flavor. Because of that he is eating much more and finally putting on weight (he was severely under weight before). In addition to finally eating for me, his fur is much more full and soft. His allergies also seem to be a bit better and he isn't scratching as much! I highly recommend this product!

Rated 5 out of 5 by from Irresistible to kitties! I've used FortiFlora Probiotic for a couple of different issues with my cats. I had a diabetic kitty who also had kidney disease and when he refused his food I'd sprinkle FortiFlora over the top and he would eat just about every time. I've also used it during food change-overs to assist with digestive upsets like loose stool or diarrhea. Kitties seem to love the taste and it works very well to improve loose stools.

Rated 5 out of 5 by from Helps bowel function with Weruva Pumpkin Patch and Feline Forte Flora Using a bit of this sprinkled on wet cat food with Weruva Pumpkin Patch Up really helped normalize my 20 year old cat's bowel function--form and frequency! A little bit on each meal along with alittle bit of the Weruva Pumpkin Patch--small meals to digest. Also found the right canned food. That was Merrick and Core Turkey formulas. Please know that the Duck and other cat foods that are marked 'limited ingredients' did not resolve Bean's problems.

Rated 5 out of 5 by from Good item to have in case of diarrhea One of my cats was having "explosive" diarrhea and nothing else. I was not worried because he was drinking and eating... just having soft stool. So I got this supplement and put it in the wet food. Within couple days all is back to normal. Great stuff!!! Expensive but worth it !!

Rated 4 out of 5 by from Cat likes it, but doesn't seem to have helped a lot Bought this due to my vet's recommendation after my cat having runny stool for several weeks. I put this on my cats food. She doesn't get fed a lot so it seemed like a lot of powder but she likes it enough to lick it out of the bowl. She tends to breath it in and will sneeze some while eating. I haven't seen much improvement in her bowl movements, still runny diarreha. But time will tell. Overall would recommend because my cat doesn't hate it so it wasn't a waste of money.

Rated 5 out of 5 by from Has been a great tool to encourage both cats to eat. My cats love this stuff. They just see me take out a packet and they run to their food. I found out the hard way not to leave the box within reach of cats. They got into a box and punched holes in a few of the packets trying to get some.
