    • It works!!!
Size: 30 Count (Pack of 1)
Review Image by Brandy N Wortham
Winner! This is a powder packet of yummy liver tasting probiotics that you can mix in cat food or warm water and cats go crazy over it, even my super picky cat loves the taste and eats more of her food when we add it to her treat of broth/stew. We have been feeding each cat half a pack so one pack a day total because we have two cats. The new kitten (6 months) was gassy when we adopted him and his bowel movements stunk bad, and he had a fishy breath compared to our other cat who had a clean breath. Sometimes he had runny stools although this issue mostly resolved after he had been home for a few weeks so we mainly purchased because he was gassy and that was not improving. The gas smell was wicked bad, I thought only dogs could have gas that bad and we had adopted him about a month prior so we aren't sure if it's related to the diet change. Instead of taking him to the vet, we decided to see if this probiotic supplement would help the issue first and so far it's working. We noticed a clear and big difference in about 3-5 days use and fully resolved within a week or two. We have only been giving him a half a pack a day because I saw it was recommended for kittens under 1 to get about half the pack. We have also been feeding half a pack to our senior cat who really didn't have any issues besides the occassional puking incident which by the way she hasn't puked since being on the probiotic and before she was puking twice a week on average and she seems to be eating more. It's a win-win for both the kitten and the senior cat so despite the high price tag, it seems to be worth the money. You can feed a half a pack a day and get 2 months per cat so the price isn't too bad for the benefits. If half a pack doesn't work then you can try a full pack. Some people purchase for pretty bad diarrhea, constipation or GI issues and I assume maybe they could benefit from the full dose. My biggest concern was that my cats wouldn't eat it, our senior girl is SO picky but you have to know if she likes it then I assume most cats would. I've read reviews that people have just added the packet to warm water and their cats love it this way and drink more water with this liver probiotic pack added (seems perfect for senior cats with kidney issues) to get more water, plus probiotics are beneficial for more then just gut health. Probiotics are beneficial for the immune system and urinary tract health too. I personally take probiotics sometimes because it's one supplement that's always been beneficial. I hope it works for your cats like it has helped mine. ❤️ Update: I normally don't come back to update and let me clarify that I paid full price for this after reading reviews to see how people liked this product because I needed something for the kitten and his awful gas. This is one of the few products I've probably ever purchased my cats that I absolutely swear by. It absolutely works 100%. This is saying something strong here. I've even changed my kittens food out to a new brand and he's not having any issues with the switch. People leave positive reviews and normally I get the item and it doesn't work as well as expected so I have come to get my hopes up. This is not the case here. Florti flora is working flawlessly. My kitten has not had a single episode of gas. None. In the past I could pick him up and he would pass gas or just randomly pass gas. No more putrid gas. The litter box doesn't smell as bad as it did. The senior cat hasn't gotten sick once (yet) which to be honest is surprising because I've bought her countless brands of food to combat hairballs and such but she never got sick much but maybe twice a week. I was not planning on repurchasing because the issue is completely resolved and I really want to see if they still need it but I'm going to buy another supply just because the cats are addicted to this, they think it's a treat. I also switched the kittens food up so I want to continue to give this one more month and I think that's all I'll need to purchase this for. I just wanted to let you guys know that this really does work and has saved me a trip to the vet. ... show more

    • My CAT APPROVES and LIKES IT! 😸
Size: 30 Count (Pack of 1)
Review Image by Cloud Nine
Review Image by Cloud Nine
My cat likes it! 😸 My cat had to be on an antibiotic before and after dental surgery for a dental cleaning and infected teeth, and to have a couple of teeth extracted. She was on Enfrofloxacin prior to the procedure for five days and then put on Clindamycin (Clindaguard) drops for 10 days after her procedure. I noticed after two day two of being on the Clindamycin, she started to get diarrhea. She was being put through enough so I wanted to try to alleviate any tummy trouble. I turned to the internet and discovered this probiotic for cats. I called up my veterinarian and asked if I could administer this to her. They said it's not a problem but, just be sure to wait at least a minimum of 2 hours after administering the antibiotic so they don't fight each other and the antibiotics kill off the probiotics. I'm very happy I found this for her. Her symptoms were relieved after a couple of days of being on this and I intend on continuing it until the packets are gone. I can already tell a difference in her mood and it's probably because the infection is clearing up and bad teeth have been extracted, and I'm sure it's helping her tummy, too. Also, she loves the taste of it! I add half a packet to a Friskies lil soup in the morning and then half of a packet to another Friskies lil soup in the evening. She laps it all up and probably wonders why the lil soup tastes so good. Although, she loves those too. Those have been an absolute Godsend through this dental procedure (2nd). In addition, I've added water to the Fancy Feast Gems pate to encourage her to eat. Works wonders for hydration , as well. It's only for 2 weeks and then she should be able to go back to her kibble and dental kibble, as well. Anyway, my cat likes the taste of this (liver flavor) and it's doing what's it meant to do - harden up the stools and help her tummy feel better! 😼 Great probiotic for cats! My lil buddy APPROVES!! TEN STARS! I think it's a little pricey. However, it does what it's supposed to do and thats what's really important here! Edit: A little over a month later and I was putting the probiotics in her Lil Soups once a day, but now I only use half a packet daily. Now that she is off the antibiotics, there has been a noticeable improvement in her stools than compared to before using the probiotics. We are almost finished with the probiotics. And, I want to see how her stools are after a few days of being off of the probiotics. This will make up my mind on whether or not to continue them. However, by only using half a packet for "preventative maintenance", they go much furtherbthan using a full packet daily. However, I would use the full packet if she needs to be put on antibiotics again in the future. Thus far, I highly recommend this probiotic. No side effects and seems to work very well! ... show more

    • Cats enjoyed it, smells good, and works!
Size: 30 Count (Pack of 1)
Cats enjoyed the flavor, some eating their food better with this in it! I bought it for my 8 cats that were recovering from worm treatment. And they always get a mild upset tummy from that, this is now something I use monthly! If I notice any digestive stress, would recommend!

    • It costs less, cat loves the taste, and it cleared up his gastrointestinal issues in 3 days!
Size: 30 Count (Pack of 1)
I tried several other brands of probiotics for my 13 year old cat who started having diarrhea over a year ago and none of them worked. I was spending $80 a bag for prescription dry food, and over $2 a can for wet food to put the probiotic powder in. None of it even helped a little. He was dripping diarrhea as he walked through the house and I was constantly cleaning carpets, hard wood floors, and furniture. I had to change my bedding daily and I was at my wits end. I took him to 3 different vets and tried everything they suggested. Then I searched online one more time because I thought I couldn’t be the only person that had dealt with this issue. I found a lot of positive reviews for Purina Fortiflora and decided to give it a try. Within 3 days the diarrhea that had lasted over a year stopped. I give him half a pack in the morning in his wet food and the other half at night. He hasn’t had diarrhea in over two months now. This product actually works and it costs less than most of the other probiotics out there for cats. Try it! You won’t be disappointed! ... show more

    • Great but doesn’t help with constipation, the PRO version does
Size: 30 Count (Pack of 1)
Review Image by Wolvy71
I took my cat off dry food and she started to get constipated. I got the FortiFlora hoping it could regulate her poop, and even though my picky cat liked the taste, it didn’t help her constipation. I then read a review on the Purina website about the PRO version helping with constipation. I ordered it from Purina and within two days, my cat was back to having regular soft poops. The difference is that the PRO version contains psyllium husk, which the dry food also had. The packets are therefore a bit larger. You can give psyllium husk separately, but I much prefer serving one packet that also includes the prebiotic/probiotic. ... show more

    • Good for constipation too
Size: 30 Count (Pack of 1)
I want to encourage pet parents who are struggling to deal with their pet's constipation to try this Pro Plan Veterinary Diets FortiFlora. It seems diarrhea management is stressed without much if any mention of constipation. As a result I ignored this item while my cat could have been much more comfortable sooner. Since it is a probiotic perhaps we should assume it would serve each purpose but many will not. I am committed to good health issues but I did not make the connection either. Perhaps more cats have diarrhea for many reasons including food choices, still a mention of constipation would be helpful to all. My cat's problem was not his good quality food but rather he became unable to process his fur. This meant his diet had to be adjusted as he is also an older cat. Something was missing however until I added this Pro Plan to his food. Problem solved!!! I sprinkle the whole pack over his food daily, splitting the powder into two servings. He eats this first then his food!! I am so happy I tried this. The gist of this review is try it if your pet has either problem. ... show more

    • Fortiflora is fabulous… Forget Dinovite and switch to Fortiflora instead!!
Size: 30 Count (Pack of 1)
This is a lifesaver when your cats have eaten aflatoxin-contaminated commercial cat food like Rachael Ray Nutrish or Friskies wet cat food and get the runs, GI discomfort, and/or lack of appetite. Their synptoms will abate noticeably in a day or so. If your cats have also been peeing outside the litterbox in addition to the runs, it will stop that as well because peeing outside the litterbox is tied to their discomfort. I used to give my cats Dinovite (a probiotic nutritional supplement you sprinkle on their food like the Fortiflora) and it worked great and kept my cats in wonderful health for years until they changed the formula a year or so ago. Now it’s garbage. My cats have accepted it less and less over time and now won’t touch any food I put it in. Not good optics for Dinovite. They readily accept the Fortiflora!!! I’m switching over and putting my cats on a regular daily regimen of Fortiflora now, no longer just when they get the runs. Purina, PLEASE don’t change the formula!!! PLEASE!!!!! ... show more

I recently found a kitty in my colony that was not feral. Upon securing her and waiting for the microchip company to contact her original owner (who lost her four years ago and was so happy to hear she was found) miss girl was struggling gastro wise while re-acclimating to the indoors. Her new steady diet of Fancy Feast was also throwing off her stomach. Sprinkling this in her food did the trick! The finely ground texture of this small bit of powder wasn’t even something she seemed to notice! It was so easy to use. I simply ripped open a pouch and sprinkled it right on top of her wet food. The amount of powder seemed to be the perfect size to add to the top of one can of fancy feast. She seemed to have no problems digesting it. In fact, her stomach seemed to even out within a few days. Before I purchased this, she struggled through about 10 days of diarrhea. I had used FortiFlora before with some of my foster kittens with success as well, so I purchased it again for sweet Izzy Bear. She is now diarrhea free! This was also the case for my foster babies who had bouts of diarrhea after weaning. I have included some cute pictures of Izzy post-FortiFlora treatment! ... show more
