Questions & Answers

46 Customer Questions

Is this high in iodine?

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.

Buffy is a rescue older cat (13 yrs?)that I have had for 3 years. He had many digestive and bowel issues when I found him. Over time I have found a bowel/constipation/tummy routine along with regular brushing that has stabilized his issues and he absolutely loves it. Every evening he gets 1 capsule opened of unflavored Metamucil, 1/4 teaspoon Mirilax, 1/2 pack of FortiFlora and 1/2 liquid tuna treat mixed with a little water to a slurry. This has produced a daily soft formed stool with much decrease in vomit. I have used FortiFlora to assist with other medication administration over the years. Of course check with your vet before any home remedies.

This probiotic supplement has been the only thing to permanently remedy my cat’s chronic diarrhea. I tried other digestive supplements and sensitive digestion foods, which either didn’t work at all or would stop working after a few days. I felt so bad for my poor kitty. I wish I tried these probiotics sooner and kick myself for thinking they wouldn’t work. I sprinkle one sachet onto my cat’s daily wet food meal and he eats it up. Within 2-3 days of starting the probiotics his “movements” were formed and they have continued to get better over the last ~20-30 days. I will absolutely buy this wonderful product long-term if it continues to work.

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.

This helped my senior cat feel a little more normal before he passed. He ate it for about a month and then he stopped eating it and most other food, but that was because he was ill. I’m really convinced this food helped him not be in pain the last month he was around

I first started using this when I had a boy with GI issues. Along with special food, this helped him keep his stools more formed. When he died, I quit using it, until my old Calico, Ayami, started having runny stools from the antibiotics I was giving her for a UTI. Between this and something from the Vet, got her straightened out. However, she is very susceptible to loose stools, and she's 17. So I give her some every night in her wet food. My son's cat, also a calico, Lorelei, is getting up there, so I put it in her food as well now. She gets pukey, so it seems to help her a lot.

I took in Elsa, a beautiful but very gassy cat, last November as a stray, and the vet informed me she needed probiotics, but they are prohibitively expensive when purchased from the vet. I am so glad you offered the same item at a more reasonable price. She truly needs probiotics every day.

My kittens were already on this when I got them, so i figured I'd continue. They both have occasional issues with loose stool, and I've realized as I've made slight adjustments that this really does help. I was splitting 1 pack over the course of a day for them (aww one just came to sit in my lap!) at first, then i tried giving them half a pack each only at breakfast, and now I'm basically just sprinking some on each meal and using between 1 and 2 packs a day (aww the other one just came and sat on top of the first one in my lap!). I could tell a huge difference when they weren't getting it with every meal- a lot more inconsistent stools. Very happy with this for now, although I've become aware that there may be better all around probiotics for cats (with more types of bacteria for their gut- I believe this just has one type). If you have a kitten with loose stool, definitely this is worth a try, and I'd say some with every meal from my experience.

The flavor of this is known to be a great topper to help stimulate appetite, though that's not the intended use. It was really helpful for my cat that had kidney disease. I would sprinkle some on top of her food. I didn't need to use the whole packet. I didn't use this for the intended use for the benefits of probiotics, so I can't speak about that, though it's impressive that the company guarantees the amount of live probiotics in the product, which most probiotic producers don't do; even the ones designed for humans.
