It was PURRfect!!!!
I would recommend this product for various reasons:
A: The product comes with plenty of chews
B: My cat willingly ate and liked the flavor
C: It calmed her down so she wouldn’t be meowing the whole way down the road
It also interested me because it didn’t have any harmful ingredients that would make her sick. It generally takes 20, 30, or at the most 40 minutes to sink in and make your cat calm. If you want it to have a chance of working better, you could give your cat 2 chews. They come in a fish shape so they may be to big for a kitten to eat. I wouldn’t recommend giving your cat more then 2 a day. Overall, I think this product worked very well

These really do work
This treats really do work. I run a local cat rescue and have recommended these numerous times. Afterwards the people come back to thank me for showing them these treats and how amazed at how well they worked. I see some reviews saying they were hard. They are hard because they are old or air has been allowed to get to them. These are a very nice tool to have when you have a cat with emotional or behavioral issues.

My cat loves these treats. They helped on a recent road trip from CT to FL. She mellowed right out, but did not act sedated in any way.

wish you got more for what you pay
It works but for the price they could give you more than 21 in a package. And why do I have to order online why don't they have it in stores? I would have gone through Petsmart or an animal product based store like that but everything is for dogs nothing for cats.

Not soft chews, but work
These chews are too hard for my cat who has trouble chewing hard treats. She usually swallows her treats whole. The first time she tried to chew and then swallowed. She found one laying on the nightstand and snuck up and got it , that one she chewed it in bits and ate it all. But won't eat any now and I have to crush and put in her food. Now to the good part, they do work to mellow her and she has went 3 days without hissing. I did not give to her for 2 days and she started the hissing last night. Back to the chews tonight,. but I would like them to be softer.

Great for my VERY nervous cat!
One of my cats has always been very nervous, and timid of everything. He's the kind of cat that will enter a room every day as if walking on egg shells. Just recently we start dog sitting in our house and although the dogs don't bother him, just knowing that there is a dog in the house bothers my cat tremendously. He paces back and forth, his pupils are dilated, he will hiss at anyone, and he wont eat or drink. He only gets this way when we dog sit, which isn't very often. So I decided to get this product. I gave him two, which he ate with ease. I did two because the first time I only gave him one and it didn't seem to have an effect; he was still very paranoid and anxious. Two was much effective on him. He soon became his old self and started eating and drinking again, and allowing people to come around him. He wasn't tired at all, but the complete opposite: curious. I would recommend this product.

I gave it to her 30 mins before car rides and it worked like a charm!

Helped with aggression
I have 8 queens (5 rescues). Recently had to put 3 on Prozac - 2 for nervous marking; 1 for aggression towards the nervous Nellies. Prozac worked for the 2 wetters but only slightly diminished the aggressive behavior in the third. Rather than continuing on to a heavier duty prescription med; gave GNC Ultra Mega Relax to the aggressor with success!

She gets it once in the morning w/ other treats like her sisters (I have to palm it & give separately because they ALL want it). Depending on her behavior during the day she may get another in the late afternoon w/ their second set of treats.

I am pleased with the results.

It has been more successful than the Prozac & after some behavior modification, I hope to be able to discontinue using it. I will continue to keep a supply on hand in case of relapse & also to give to my nervous Nellies prior to vet visits.

Won't be without them....
I am not qualified to make medical claims, but these work for my cat who has feline hyperesthesia. I give her one chew as needed and she is calmer within minutes. She doesn't need them every day, but on her bad days, these WORK. I highly recommend.
