cats will not eat them

Unfortunately none of my 3 cats would touch these. They smelled them and walked away.

Not sure about these

I purchased these in hopes of Buddy chewing them and he was going to be good to go for a road trip and be calm the whole way. I decided to try them before and see what he thought about them. Well, sad to say he did not care for them at all, chewed one and that was it...would not take another one. I also purchased the paste and did not even attempt it. I'm sure it others would enjoy them and they would do the job...Buddy is very picky on what he eats so I can't really rate these.

Godsend for kitty anxiety

My grandkitty is absolutely terrified of thunderstorms, fireworks, even just rain hitting the windows. He used to run to the basement and hide, but after purchasing the calming chews, he will stay in the living room with us...apparently he likes the taste of them as well. Note: this kitty WILL NOT wear a thundershirt..we've tried..he falls on his side and plays dead when it's the calming chews have been a godsend for my anxious grandkitty.

I was looking forward to these treats as I have one cat who gets stressed extremely easily. But these treats smell absolutely horrible and both my cats want nothing to do with them. Don’t even know if they “calm” because my cats would rather leave them alone.

Waiting to test the calmative affect.

We will see on an upcoming trip to the vet. I tested one and he ate it. He is picky so I was glad of that. This will be so much easier than smearing something on his paws.

Not so much

My poor Missy is so scared of thunder and still runs under the couch at the slightest bit of thunder

Saved my life!!!

OMG, thanks to these treats I now FINALLY can sleep at night. I give 2 treats to my cat before going to bed and I sleep like a baby. My cat was meowing at random times of the night, sometimes at 4am and this was driving me nuts. He is now quiet, sleeps on my bed and I finally have my sanity and my life back. Thank you!!

Not a significant difference

It’s a tricky treat to give my cats because every night is different. The reviews say it takes awhile, but after several weeks they still go crazy at night and when they don’t it’s because we keep them up in order for them to actually sleep at night. It stinks because the directions say not to do it every night, so it’s hard to get a routine going. They do enjoy eating them, but we have to make sure one cat doesn’t get two because that’s also something the directions say. We ended up having to try other options because it’s not a significant outcome that has solved our problem.
