Check with vet first

First I am not warning anyone about this product UNLESS YOU HAVE A DIABETIC CAT!!!!! My vet told me to get forti flora for cats because the rx food he eats stink soo bad, but I had already ordered this. About a couple of weeks following instructions to the letter my cat stopped eating, drinking and using the litter box for 4 days, I was already looking for a vet to euthanize him at home, on the 5 day he started eating and everything, I started doing research and it’s these enzymes/pro/pre biotics , same thing was posted here about Forti Flora. I have contacted both Purina and this co to let them know. I will no longer give my cats anymore vitamins or anything they are just not built like dogs, another expensive vitamin kept making my cats UTI worse. I sprinkle a smidgen on the cats food when he gets diabetic med only and every couple of days. My Belgian malinois gets a smidge too.

Belly issues

This product has truly helped my 6 year old black mouth cur to be able to digest her food. I had to also put her on a stronger med because her pancreas is small and under functioning. I will be giving her both and hope she puts on some weight.

Beware if your cat is diabetic

My diabetic cat eats DM and takes medication for his diabetes, stool SMELLS big time, vet recommended forti flora for cats , chewy didn’t have (read what someone posted at forti flora for cats and diabetes) I tried this followed directions to the letter and after a couple of weeks my cat went without food or water or medication for 4 days was getting ready to put him down, thank god he decided to start eating again I sprinkle a pinch in his wet food once a week and share with with the dogs and other cats till it runs out. My opinion it’s not that the product is dangerous I think I has something to do specifically with diabetic cats, will deal with the smell. I have a finicky Belgian malinois that can go 3 days without eating and gets people probiotics I buy at Amazon.

Literally the best thing ever for cats

If you have a cat who refuses to drink and have constipation, PLEASE please please get this. I moved back the States few months ago with my 2 year old cat who's consistently had a digestive issue... mostly due to her natural low water intake but also because the environment drastically changed after moving - cats are sensitive to their surroundings. I assumed this would happen and brought a box of prebiotics that she used to take before moving which solved her constipation, but the symptom appeared again nonetheless. There was also a British fiber supplement I used before but it was extremely difficult to feed it to my cat (I had to crush it every time & the flavor she did not like) and it's also hard to find it here in the US. The loose powder is so easy to feed and my cat actually thinks that it is some kind of treat because she likes it so much! (This is the best part, since it is difficult to find a supplement that suits my cat's taste)

Did not like

My cat Brady did not like it and refused to eat his food with the stuff in it. Maybe another cat would like it
