Ohhh sooo happy this works
I have a 14 yr old kitty with dementia. Poor girl howls at night and wakes us up cuz she forgets where I am. This has been a game changer! And it saved me from being kicked out of bed and sleeping on the couch lol

A Good Alternative
I just got new cats and one of them is a little more skiddish than the other so to help calm his nerves and help him relax I tried these and luckily he loved the smell and taste while the other cat did not. I saw no diarrhea or adverse effects to their fecal matter and he only threw up once which I probably gave him too many snacks. I would say it is effective in helping calm him since he just took some naps. A nice and compact jar and the size of the snacks are decent since my 1 year old could eat it once I broke it up since it is nice and soft which he is picky and totally could have eaten it himself. Overall it is a good price for the quality and quantity you receive.

Our cat loves these, but it’s definitely not calming
Our cat goes bananas over these! Translation: he goes ballistic, and does not calm down after consumption. He’s a normally chill cat, so it was interesting how there was actually an opposite effect. We can’t really tell if there is that “gut boost” effect, but I expect it’s more of a long term thing anyway.We use this more as a treat now, so it’s not really a waste, but if you’re paying for that relaxation bit, this is not the way to go. At least, that’s our experience with our kitty.

One of my cats liked him one of them didn’t, but the calming has yet to be seen
These are soft cat treats. One of my cats liked it and one of them did not like it, which is not a surprise. They seem to have opposite tastes. They smell pretty much like cat treats. They seem to like the taste of it overall. There is no itch control in these are meant for calming, however The type of calming that they do is usually very subtle so it’s hard to tell right away. The sheet should last a while. I don’t feel a lot of them overall. The ingredients that are listed are shown to be effective in calming cats sometimes. It could work for your cat, but it could not. It does not affect shedding at all.

Zen Tummy Chews, But Maybe Add Tuna?
These soft chews are a dual-purpose cat supplement designed to work on both promoting relaxation and supporting better digestive health for your feline friend. I appreciate that they included pre and post-biotics, along with essential enzymes, vitamins, and minerals, which really seems to back up their claims regarding overall immunity and gut support. The dosage instructions are super clear and easy to follow (it depends on your cat’s weight), which is always useful when introducing new supplements. My cat isn’t exactly thrilled about eating the chicken flavor right out of my hand, but crumbling it into their wet food works just fine. While I need more time to observe if the calming aspect is making a huge difference, I feel good about giving them something that targets their overall wellness. It seems like a very solid formulation based on the ingredients list.

He doesn’t have the brain cell
I have an orange 3 year old who is pretty hyper and high-energy and never met anything vaguely food-like he wouldn’t eat. He scarfs these up, but again he’s not picky. You get about a month’s supply when fed as a treat, so they should last awhile.I can’t say for sure whether they have calmed him down or affected his digestion, but he loves them.

My cat thinks they’re delicious but doesn’t seem especially calm
I offered this to my two cats who are brother and sister first, but I didn’t expect them to be interested because they do not like wet food or treats, only dry food and water. I don’t know what’s wrong with them, but I was correct and they made no attempt to eat these when they were offered. I gave one to my much angrier cat, who is much less picky, and she bit my fingies in the process of devouring the first one and then screamed for more. I dropped the second one, which she was mad about, but I gave her another so she didn’t have to look for the second one. The instructions advise administering these supplements by weight, with small kittens requiring only one piece and larger cats needing as many as four; however, it suggests starting with a half dose. I actually meant to order the urinary version of these, but I guess it’s for the best that I didn’t because my cat who has had a urinary blockage previously is the brother who isn’t interested in treats or wet food, so they probably would have gone to waste. My angry cat is stomping around the room now so I’m not sure that it calmed her down any, she was curled up in a ball before getting all hopped up on these. As far as gut health, I’m sure it would take time and consistent use to notice any changes in poop, but she poops fine as it is. Mostly interested in the calming effects because she’s a sharp marshmallow princess with claws. She’s also a little bitey.
