Review: Cats are addicted ! - My cats love this powder and want it at every meal. It contains L theanine and I originally purchased it from my vet to relax an anxious kitty who suffered from incurable idiopathic cystitis. now he has no more issues and I use this powder to entice him to eat when it’s not his favorite food. They both love it as a treat especially in the evenings, so they are less inclined to disturb us with the zoomies. Relaxes the pets and improves appetite. I always have it on hand.
Review: CAREFUL!!! IT RAISES SUGAR GLUCOSE LEVELS - I am shocked as to how well Purina Calming Care for cats has worked!... I adopted an abandoned 1 yr old VERY large 15 lb (un-neutered) male kitty 1 1/2 yrs ago & got him neutered immediately. The challenge was I already had a super mellow 11 lb 15 yr old male cat that the young "brute" despised... Right out of the starting gate the new male addition began attacking my older boy on a regular basis. I knew he was very jealous of him. Un-fortunately, my 15 yr old cat was being bullied weekly by the young male. I tried EVERYTHING from pheromone collars, diffusers, sprays, shock collar (1 week), & CBD oil, & none of these things would stop the brute's weekly stalking attacks. There were more than numerous occasions I felt I would have to re-home the new cat. (Last week's attack on my 15 yr old was so brutal that I had planned to surrender the young male cat to the SPCA the next day.)... Later that same night directly following the attack, I read an article about Purina Calming Care. It almost sounded too good to be true & too simple to work so well. But, what did I have to lose? After all, I had tried everything else.... I have been giving the young male cat 1 packet of the Calming Care sprinkled & mixed into his wet food every early evening for the past 5 evenings. (I chose the evening time to give him the Calming Care because 95% of the time his "Bully Attitude" / attacks would happen in the evenings & outdoors where he would "ambush" my older male cat.)... Well, I'll be darn! For the past 5 nights, I have had a perfect young male "gentleman" cat hanging out with me on my living room couch. He is thoroughly calm & behaves like any other normal cat. He's not the amped, fired-up young "male stud" cat wanting to go outside at night to be / act like a typical, on-the-prowl, fighting Tom Cat like he use to be. Now, the young boy seems perfectly content... AND, not 1 hair on my 15 yr old male cat's body has been touched by the young "brute" in the past 5 days.... I can honestly say that I am truly baffled as to how something so simple as probiotics, specifically "BL999," which is what's in Calming Care, could work so doggone well. But, so far, it has brought a great deal of peace into my home, & has changed a cat from being a Bully to a content cat that I'm really wanting to keep... Even my sweet 15 yr old male cat is a bit confused & surprised with the peaceful change. : ) ** WARNING UPDATE: THIS PRODUCT CONTAINS MALTODEXTRIN (IT SPIKES CARBOHYDRATES & IS AS BAD AS TABLE SUGAR WITH CATS GLUCOSE LEVELS. THE SYMPTOMS RESULT WITH INCREASED HUNGER & FOOD CRAVINGS, & CAN LEAD TO DIABETES.)... AFTER ONLY (1) MONTH, MY CAT PUT ON A LOT MORE WEIGHT & BECAME LITERALLY BORDER-LINE OBESE... I WOULD (NOT) RECOMMEND THIS TO BE USED WITH ANY ANIMAL. NOT IF IT CAN LEAD TO DIABETES.

### ⭐⭐⭐⭐⭐ Cat parents: THIS STUFF ACTUALLY WORKS.
*by X***S on January 16, 2026*

My cat is an adult. My cat has always been naturally skittish. He hates company and my guests used to think he was a myth. A few days of this amd he actually comes out to see the guests every so often. His social anxiety is so much less. He lets more people pet him now. That alone is worth the price and 5 stars. Cat parents: THIS STUFF ACTUALLY WORKS.
