I bought this upon recommendation of my cat’s veterinarian. My oldest female cat had become fearful of one of my younger cats who enjoys harassing her. The roles were reversed when the younger cat was a small kitten and she was fearful of the older cat who constantly threatened her. When the younger cat grew to be an adult she started intimidating and at times becoming very aggressive toward my old girl. It got so bad that the older cat did not want to leave her safe spaces and was not socializing with the rest of the household. After starting her on the Purina Calming Care supplement and also using some cat pheromone products she started coming out of her preferred room and actually standing up to the younger cat when confronted. After a period of time I was able to stop the supplement and now the cats can at least be around each other and my older one can hold her own without being so fearful. I really saw a positive change with the Calming Care.

Good Budget Friendly Option for Mild Cat Anxiety

I contacted Purina directly to confirm that this supplement is safe for cats with chronic kidney disease, given my concern about calcium levels. They confirmed it is CKD-friendly. Swiss is an anxious cat who startles easily and stays on high alert. While a prescription medication would likely be stronger, I wanted to try a gentler and more affordable option first. This calming probiotic has helped take the edge off her anxiety. She seems less stressed overall and starts the day calmer rather than immediately reactive. A good, budget-friendly option for cats with mild to moderate anxiety.

I have a scaredy cat who only comes out of hiding at night when we are quiet and laying in bed. The vet recommended trying this product. It is easily mixed with her wet food, it obviously doesn't add an unpleasant flavor or she wouldn't eat it, and she eats all of it. She has started being less scared--less immediately jumping and running away at every little movement. She has started coming downstairs to join the family a little more. I will definitely keep using and hope that usage continues to improve her.

My last ditch effort to have harmony amongst my cats

I have two 15-year-old cats, Matisse and Sabine, brother and sister. I introduced a kitten, Kato, into the household in November of 2024. It has been a nightmare

I have two 15-year-old cats, Matisse and Sabine, brother and sister. I introduced a kitten, Kato, into the household in November of 2024. It has been a nightmare since. Matisse and Sabine are hostile towards Kato. I tried air room diffuserd that were supposed to dispense calming pheromones. Didn't work I purchased the Purina Pro Plan supplement in addition to some "calming collars" in hopes to bring some harmony amongst the three felines. Matisse is still hostile towards Kato and there is a lot of hissing and Kato usually runs in fear. I really don't know what to do.

Our cat had anxiety and was over grooming. I started mixing it into her wet food in mid-December and by mid-January she had quit grooming those spots too much and the hair has grown back. She also is relaxed enough that she’s doesn’t run when she hears a loud noise. My vet said she recommends this product. I’m going to see if she still needs the pheromone warmers. I suspect she won’t. That will save lots of money.

Our Vet recently recommended Calming Care for my 18.5 year old kitty. He has progressing kidney disease & is going to the litter box hourly. The doctor has seen good responses from this product for calming the cat’s stress from this illness. I just started using it & he readily eats it. If he turns away from a fresh plate of food & I sprinkle a bit of the powder he eats with no problem. This is important to maintain his weight. I’ll keep using it & see if there are additional positive effects. I also appreciate the Chewy discount with autoship.

Our cats love Calm (and Fortaflora) so much we use it for ‘seasoning’ when we’re transitioning foods or in the case of our kitty w/ kidney disease not wanting to eat his bland prescription foods. I think it does help calm them too- we add to our cats food when we’re preparing to go away and have our cat sitter give it to them while we’re away. We also use it when we have house guests or before groomers visits.

I must start that NO, ZERO, ZIP cats under 2-3yrs old need to be calmed unless medically advised. If you chose to go homeo/natura pathic, that is your choice. My Bea was finally diagnosed with Feline Idiopathic Cystitis just this year. 9 fuqing years of vet bills and $$ upon $$. I had to tell her vet what I was suspecting and it's the final of all of any of usually undiagnosed disorders. So far, this hasn't helped as touted. I'll give it 2 more weeks.

We have a younger male cat that constantly bullies our senior female cat. The vet suggested trying the calming care supplement. Around the 2 month mark it seemed like he had calmed down some and was leaving her alone more than he was bullying her. Unfortunately, it didn’t last. As more time passed, we gradually started seeing him harassing her again. Now he’s back to bullying her every day. The only benefit that we noticed after he started taking the supplement that has lasted is that his fur is softer than it used to be.

I started administering this supplement two weeks ago and my anxious cat has not sprayed on the sofa since! Her aggression towards her feline siblings remains consistent, but I am thrilled with the behavioral progress otherwise.
