Questions & Answers

40 Customer Questions

What type of good bacteria is provided in this?

Can this be used as a bribe to get cats to eat raw food?

Answer by Chewy • Apr 23, 2018
This supplement is not meant to entice your cat to eat a certain food. It is intended to be a digestive aid, supplying the healthy microorganisms needed for good digestion.

Weill this product do anything to help with a furball issue?

Answer by Chewy • Mar 23, 2018
Probiotics and enzymes help maintain a healthy digestive system and helps to prevent any potential diseases of the digestive track. They will also help your cat pass any undigested food that tends to attach to hair sitting in the digestive track, thus helping him pass hair before it becomes a hairball.

What's the shelf life on this product please?

Answer by Chewy • Aug 28, 2018
The shelf life of FortiFlora is 18 months from the date it was manufactured. Refer to the "Best if used by" date on the package.

My cat loves this stuff. We put it in her food with her GI lymphoma medications and she freakin mows it down. I think it’s just pure concentrated meat flavor. it makes me want to put it in my soups as the human in this situation my only real issue with this product is that the default dotted line shows that you have to tear the right side of the package where the picture of the cat’s head is to pour the powder out. but i figured out an alternative solution by tearing the opposite corner.

Noticeable improvement in both cats

Our Nebelung has such a sensitive tummy. The only thing we could feed her for years where she wasn't constantly getting sick (I mean throwing up and hiding under furniture and crying) was raw- Stella and Chewy's. I'm really grateful for that diet, but after many years we wanted to try normal wet food again, and started Purina pro sensitive skin and stomach with these probiotics. She still doesn't get sick and I think she's even doing better with this current diet. She's at a healthier weight, makes us and the vets happy. Our boy has gastric reflux so he has tummy problems especially at night and we started him on this, along with cosequin, and he's improved drastically in the last month or so from that. I like to feed both of them mainly poultry and that seems to help as well.

We just started it a couple weeks ago. At first I mixed it in but then I just sprinkled half the package on the top of his food and he is eating it. He doesn't have firm poop yet, but I do see a little improvement. Will keep it up for at least a month. He has had soft poop for almost 8 years so I need to give this a chance.

This is AMAZING! My Stormy boy has had a rough start to life. He is almost two and was diagnosed with IBD last spring. Our vet recently recommended this after his latest flare. I mix it in his wet food and he goes to town on it! I feel that it's improved his appetite as well. His sister cat also gets this as they share food bowls. She's a more consistent eater now as well. The litter boxes have also been diarrhea free! Vet recommended twice daily until the flare has eased. Now they get a packet each at dinner time. They switch bowls throughout so that's why I use two packets - hopefully between the two cats and two bowls they are each getting their fair serving.

Malibu has an upset stomach, he probably got a bug somewhere so he wasn't a happy camper. I remembered Chewy has this wonderful service that allows you to seek vet care via chat. Dr. Lina and I talked and she recommended this. Malibu got his first dose yesterday, and it helped him so much. Whatever is in this product does it's job. He took to the Gave him a lickable in a plate with this on it and he ate it up. He still has a small bit of icky but he is getting better. Stir this into their food and it works. Thank you Dr. Lina for the help and making me a less worried mamma of a little guy!!

We're still testing it but it may have helped some. My cats always seem to have an issue where they have to cough up around 4:00 in the morning and of course I wake up then and make sure that it's not on anything important. And it isn't hairballs, they're coughing up dry food or treats or a little dinner. So my vet suggested that we try this out

Love Chewy’s phone service!

This review is for all the amazing folks that operate the Chewy help line. These folks most always pick up the phone after one ring. They are upbeat and polite

This review is for all the amazing folks that operate the Chewy help line. These folks most always pick up the phone after one ring. They are upbeat and polite. They are helpful and are empowered by the corporation to solve the issue on the first call. I can’t say enough good things about the Chewy service line. Apple service line is very good. But Chewy takes customer service to an entirely different plane! Thank you!
