My cat, Sophie, was experiencing constipation recently, but prior to that, she had been successfully eating Science Diet Feline C/D dry for years. She was given two enemas on two separate days by our veterinarian before I finally realized that it could be the C/D. We switched to Perfect Digestion dry, and she hasn't had a problem. She begs me to put some down for her. She is addicted in a good way. The C/D did serve her well for a very long time, but she is now almost 15 years old, so her needs have obviously changed. I hope this review helps someone else.

They changed the formula or something!

I’ve been feeding Hill’s brand my cat for years. I’ve heard about Hill’s changing formulas with their pet foods. My cat gets serious diarrhea with this food now

I’ve been feeding Hill’s brand my cat for years. I’ve heard about Hill’s changing formulas with their pet foods. My cat gets serious diarrhea with this food now. I had him to the vet and spent over 1000.00 dollars, had his teeth cleaned, medication, prescription foods. Got him better and the Vet said put him back on his regular food so I just bought a new bag of Perfect Digestion 7plus and started very small and wham diarrhea first thing this morning.

To bad he wouldn’t eat it

It’s a no way, no how kinda deal here. Bought this because my Siamese cat pukes almost everyday. Maybe my fault because I didn’t transition from one food to this

It’s a no way, no how kinda deal here. Bought this because my Siamese cat pukes almost everyday. Maybe my fault because I didn’t transition from one food to this food but I was out so I just gave this food. I can say it did help with the puking because he wouldn’t eat it ugh! All cats are different and what one eats the other one won’t so you just have to keep trying until you get it right.

My cat kept sneaking the dog's food of the same make and model. I was happy to see a cat version available. But not as happy as my guy was when this arrived. As soon as I opened the box he went nuts and promptly ate a whole bowl (mixed with his old food of course). He ate it so ravenously that I was sure he'd end up getting sick, but that was not the case! Happy fur baby, happy mom!

My 16 y/o had been dealing with severe constipation and was on heavy miralax doses for a while. I was getting to the point of stalking him whenever he went to the litter boxes to figure out if the dose needed to be adjusted as he was jumping from nothing, to liquid, to ok, to half and half, and the not eating and losing weight with his hyperthyroidism and whatnot was becoming so hard to control. I didn't want to keep giving him miralax because the results were inconsistent and he just seemed to have an upset stomach all the time. So I decided to give this a try, within 4 days (and with just the small amounts of transitioning his food) he was pooping again on his own. It's been over a month now and he is still regular with no miralax needed. Sooo happy with the results

I live in the lower level of a two unit house. No matter how clearly I state on my address label to please deliver to my front door downstairs they never do it. So frustrating to have to carry the heavy box down everyone else can deliver to my front door except Chewy
