    50% Success

    By Spritzy on Jan 23, 2022

    We have three Siberian forest cats: 2 males, and the twin sister of one of the males. The largest male picks on the female ruthlessly despite having numerous cat trees, multiple litters in multiple rooms, feliway plugins in all contention areas, and lots of exercise and attention. At some point this encouraged the smaller male to also start picking on his sister. We started the boys on this powder. BOTH males became much more relaxed and within just a week or two of starting the powder. Unfortunately, the largest male is still attacking our female, BUT the brother cat has stopped completely.

    The boys loved it.

    By vanessa6298 on Jan 18, 2022

    I found this product to be easy to use. All you have to do is open a packet and add it to your cats' food. I found sprinkling it on top to work. The powder has a slight meaty/liver scent. The instant I opened a packet my cats were excited. The powder isn't too thick or too fine. I found that I can spread one packet amount two dishes. Overall it's the first time my cats have tried it but they loved it. I'm hoping this will help one of my cats with his skittish behavior. I received this product at a discount for my exchange honest opinion

    So far I think it's working

    By Felice on Jan 14, 2022

    We have only been using this for 2 weeks, It says can take up to 6 weeks to see results. However, we are feeding it to one of my cats who has been marking her territory for several months after getting a new kitten. We've tried all the sprays/plug ins, etc., and the vet just recommended this product. I am pretty sure the spraying has lessened dramatically, but not 100% "yet". Also, I mix it in her wet food in the morning and no trouble getting her to eat it, she seems to actually like the taste.

    It’s working!

    By Michelle on Jan 8, 2022

    My Bengal cat has been trying to kill his brother for at least a year. We’ve tried everything. Sprays, plug ins, treats, cat tree, cat wheel, slow introduction. Slow re-introduction. Nothing works. Then I started him on this and within a few days he is much better! His brother can walk around on the floor and not get attacked! And he likes it so much that he took the empty packet out of the trash just to lick it. So I would definitely recommend this to anyone who has a cat that is aggressive, even a Bengal!

    Calming Cat Calms my cat

    By cats on Jan 21, 2022

    This calming care has helped my crazy kitty from going crazy nonstop. He eats everything in site and would bite holes in a box. He cost me 1500 for removing thread he ate off my sewing machine. He still plays all the time but is not as aggressive with it on calming care. I am starting another cat on it that gets anxious and then will wet on the floor. I am hoping it will help her as well.

    This does seem to help stress

    By calm on Dec 16, 2021

    We have 10 year old brothers fighting and spraying for dominance after some pet household changes. It has helped to calm one of the boys who's been stressed and spraying the longest. He's actually been playing again in our living room, which he hasn't done for years. It's slowed down the aggression and spraying with both when nothing else we've tried has. (Pheromones, both plugins and sprays, every calming treat available, zylkene, calming collars, lots of cat towers and toys, and numerous litter boxes.) It's not a miracle and hasn't stopped everything completely, but it has helped. They also really like the taste and eat it off their food happily.

    It’s helping

    By LTig on Dec 12, 2021

    My cat has been licking a lot of fur off due to separation anxiety since I returned to work and it has become an obsessive compulsive behavior. She’s still licking, but this product seems to have settled her stomach where she’s not throwing up anymore - I think only once in the past month vs several times a week. I simply mix the powder with a tablespoon of soft food and she readily eats it. I’m trying to give her liquid form of Fluoxetine to help with the anxiety but I can’t get her to take it - even after trying many ways to hide it. I’m so glad Calming Care is providing some relief and she will easily take it in her food.

    What a difference!

    By momster64 on Nov 20, 2021

    My cat began over grooming a couple of months ago. He has always been an anxious cat, but this was a new behavior. My vet put him on Calming Care and he has responded well to it. His hair is growing back! And, I am beginning to notice his overall anxiety is better. I wasn't sure if he would take to it, as it is sprinkled on the food but he loves the taste. Keep in mind it can take up to 6 weeks to see results, but I saw a change after 3. Definitely worth a try!

    More than I had hoped for

    By MeowMeowYes on Nov 25, 2021

    We have a foster cat that is always grumpy and anxious. We tried a calming collar that helped some but when we added this product as well, the results were amazing (within 3 days). She no longer grumbles and growls. She is more loving, seeks pets, and tolerates the other fosters much more. I'm more than pleased with this product and will be trying it out on our cats that are on anxiety medication.

    Stressed out cat

    By Catmom on Dec 20, 2021

    I have a very stress cat. I was using a different calming care product and a vet tech told me to try this one. I truly can’t tell you this will not work. I can only tell you my cat did not like the flavor. So I am going back to the one she will eat.
