I purchased a second box of this for my cat after misplacing the first box. The first packet I gave her from that first box caused some diarrhea with foul stools but I didn't relate it to this until I purchased the second box as a replacement. Her stomach revolted this time and she was miserable. She was frantic, worse than without the supplement. She was up all night (and I with her), miserable. While this seems to work for some cats, I will never give it to her again. She was better without it. This isn't an inexpensive option, and it caused horrible side effects.

I don't normally write reviews, but I had to share my experience. I had a 12-year-old stray who was essentially feral living in our neighborhood who would only approach one neighbor who has been feeding her throughout her life. This past January, we decided to bring her inside as it was going to be a harsh winter. She was terrified - hiding, hissing, darting away. I couldn't get anywhere near her to even try to introduce myself. I tried everything I could think of to get her adjusted to me. I read in the room with her every night when I fed her. I bought cat trees, scratching posts, toys, every kind of treat, but nothing seemed to work. I have been using this product for the last two months, as recommended on the packaging. The changes in her have been absolutely GAME CHANGING! She runs and plays in her room with her toys, loves looking out the window in her cat tree, does great with my other cat, and rubs up into my hand and against my legs. She still hesitates occasionally, but I have been so pleased with her progress! I work in veterinary medicine, and I would have never thought an over-the-counter product could make such a HUGE impact. Still, consult a veterinarian before use - she has put on quite a bit of weight. I measure her food to adjust for this to prevent diseases such as diabetes. However, if you are working on adjusting a stray into your home, I cannot recommend this product enough.

I recommended this to my brother and his girlfriend. They adopted a new kitten and after a soul introduction of a month, they were just about to surrender him back to the rescue. They started using this in both the kitten’s food and they’re older cat and were shocked by how fast it did the trick! One week later, both are playing with each other, no more stress, and no more chaotic energy.

With the addition of a boisterous kitten & the death of Petey’s best friend, Petey began to hide under the bed all day, coming out only to eat. A friend suggested using Calming Care & I noticed a difference in her in 3 days! It was wonderful to see her out & about more! I had to mix it with some squeeze treats as she never finishes her bowl of food & if I mixed it with water, she didn’t drink all of it. I am going to start giving some to the now 3 yr old kitten as she is stalking Petey & I am hoping that Calming Care will work on her aggressive behavior towards Petey. It certainly worked for Petey, love having her more back to normal. She snuggles , goes out on the back porch, will let my husband pet her again!

Had high hopes but had bad reaction for my cat. Started 10 days ago to in hopes it would calm her anxiety in about 6 weeks( for that's when it days to see results). Everything was fine for 9 days and then my cat threw up multiple times two times out of the 10 days. After searching Google it says if this happens to stop due to a possible intolerance, allergic reaction or having a sensitivity to meds like this. The directions say to use a whole packet and I decided to split that whole packet into three of her meals( before any vomiting started). Well even doing this she threw up. Pull up on further review it says to start off with a pinch to get them used to this I really wish that it would have stated that on the directions. After calling my vet she said discontinue it so I don't even feel comfortable trying to decrease down to a lower dose. So I am money out of pocket now and still searching for something that will help calm her. I will say this, my cat is very very picky about food or anything that touches it. She absolutely adored the taste of these packets. Which is just more unfortunate because she really liked the taste and I Know It Takes 6 weeks for it to work but I really had high hopes I found something for her anxiety. I have tried everything such as prescriptions, Gabapentin and, the pheromone plugins, trainers. So I guess I'm back to the drawing board. Bad or I might stop it and see if throwing up subsides and then maybe start off super super slow like a pinch here and there for a few weeks. Please be warned if your cat is sensitive or you have any hesitation start off very very slow. Way slower than what it says to do. Which makes sense to me because anytime you change a cat's diet it always needs to be very gradual. Even though this is an a drastic change to the diet it is still incorporating something completely different. So I'm not sure if she just has an intolerance or is having an allergic reaction but hopefully they will return it.

one of my girls is extremely anxious. even with two Feliway plug-ins in my room she still spent most of her time hiding. I've been giving her Calming Care for almost a month and the difference is like night and day. she no longer spends most of her time hiding, she comes out readily for me and even sometimes for other familiar people. She likes the taste and eats almost all of her food every dinner. She's still anxious and shy but there's already been a vast improvement and I hope she'll continue to improve as she stays on it. Worth every penny for me to see my girl happy again. I was going to talk to her vet about Prozac before this and I'm glad to be able to avoid that experience for her. She also has a very sensitive stomach (suspected chicken sensitivity) and this doesn't give her the dreaded stinky poops! I do agree with the other reviewer saying they dislike the individual packets, it would be nice if I could buy a large tin of it with a scoop or something, and if I could buy larger quantities at a time for less price per serving. That's really my only complaint though!

It works, but I wish there were options outside the individual packets. It feels wasteful.

I read this package at the store as I was searching for something to help a stray that adopted us to get along with the rest of the crew. I tried the plug-ins and collars to help decrease anxiety but found them to be ineffective. This product stated it could "help promote positive behaviors such as playing and seeking out social contact", and that is what it did. I have a lot of cats and only one that was really struggling to mix with the group. Her social skills were amazing with us but not other cats. We found her abandoned in a parking lot that is noted for people who dump their animals. After the first day of this product there was a noticeable difference. So much of a difference that I am curious why it works so well. For now I will keep using this so that she can continue to live a happier, fun filled life instead of one that is always on the defense.
