Made a big difference for my FLUTD cat!

I brought home a new kitten a while ago that unfortunately my 5 year old female was NOT a fan of. He has no manners and she despises him. She got 3 UTIs in the months

I brought home a new kitten a while ago that unfortunately my 5 year old female was NOT a fan of. He has no manners and she despises him. She got 3 UTIs in the months after bringing him home, even after switching back to her urinary prescription food. After adding this in the UTIs haven’t reoccurred and she seems to tolerate him much better. I don’t think they will ever be best friends but I have noticed a huge difference on this supplement and I do notice a difference when I stop it then restart it too.

Works once I bribe picky cat

My cat won't eat these unless I have a high value treat that I give alongside it. I think they do work once he eats them. I give them to him for general nighttime

Recommended by my veterinarian for my "domesticated" feral kitten.

My little guy was bottle-fed from 4 weeks old and not raised around other cats. He can be feisty and, sometimes, angry. One chew every day and half has calmed him

My little guy was bottle-fed from 4 weeks old and not raised around other cats. He can be feisty and, sometimes, angry. One chew every day and half has calmed him down and made him so much easier to live with!

It works very fast as the pack says. Oliver and Opal can be on the aggressive side, while Claire and Barney are on the shy side. Mellowed everyone out. They get it first thing in the morning with their food. Everyone getting along much better.

If she would eat them, I think they’d work

My oldest cat has always been a bit excitable. The reviews made me give this a go, but she won’t eat them. My two already chill boys ate them and loved them, then

My oldest cat has always been a bit excitable. The reviews made me give this a go, but she won’t eat them. My two already chill boys ate them and loved them, then proceeded to chase each other around the house (they don’t usually play with each other). I think they probably work, but if the cat won’t eat them, they definitely can’t. I gave one star because the intended recipient is too smart to eat something that will make her less of a basket case

He did not like the taste.

They worked great. But he would not eat them. I had to crush them up and sprinkle on his food. Would be great if they sold this item in that way.

Too hard

This was supposed to be a chewy but was too hard for my cat to eat. She has very few teeth so I have to grind up the piece and sprinkle on her food.

My vet recommended these

My cat is extremely anxious, so much so he pulls his hair out in patches. Giving these to him consistently has calmed him down so much he pulls the hair a lot less

My cat is extremely anxious, so much so he pulls his hair out in patches. Giving these to him consistently has calmed him down so much he pulls the hair a lot less and in less quantity.
