Questions & Answers

13 Customer Questions

Is this able to be used with the “FortiFlora” digestive blend, or does the probiotics in this “Calming” blend suffice by itself??
Answer by ChewyOct 09, 2021
FortiFlora and Calming Care utilize two different strains of bacteria, Enterococcus faecium (SF68) and Bifidobacterium longum (BL999) respectively. Different strains of probiotics have different effects on the body. The promotion of normal intestinal microflora produced through use of FortiFlora specifically targets gut health and gastrointestinal related issues, such as diarrhea. Calming Care, by contrast, communicates with the central nervous system where it has an anxiolytic effect on the pet. In other words, the benefits from FortiFlora are different from the benefits from Calming Care.

How long should this supplement be continued? Will my cat go back to being stressed if I stop using it?
Answer by ChewyMar 16, 2022
Calming Care has been shown to be efficacious after 6 weeks of administering one sachet per day. Calming Care should be taken on a daily basis and not as a short-term anti-anxiety solution for sporadic stressful events, such as fireworks, but as part of a multimodal approach involving behavioral and environmental modifications. Once the probiotic is no longer being administered, the previous behaviors will likely return.

Hi. What is the source of the liver?
Answer by ChewyFeb 23, 2022
The liver flavoring in Calming Care and FortiFlora is hydrolyzed pork and poultry liver.

Is this product safe for cats under a year old?
Answer by ChewyDec 14, 2021
Calming Care is safe for cats of all ages, including kittens.

Nervous girl transits to be a refined lady

I received a special deal on this product for providing my feedback. I feed my active young cat one packet daily, simply mix it with the cat food, and she just loves it. Although it may take up to six weeks for full effect, I feel like my nervous girl is transiting to be a refined lady. I'm so satisfied that the supplement helps to relieve her stress, and supports a healthy immune system.

This stuff is awesome!!!

Our kitty started exhibiting some anxious behaviors and we tried extra play time, cuddle time and attention. Nothing worked. So….after reading reviews for this supplement we decided to try it. Now it is a little pricey, but I think it did the trick! I mix it in with his wet food and he gobbled the entire bowl when before he always left a bit (like the stray bits of meat etc). He love love loves the flavor and he is certainly calmer. Not tranquillizing, but not pacing like he used to. After the box is done I’m not sure if we will continue without it to see if it makes a difference or just keep it going because it does work!! Get it!

Picky Eater

My cat is a very picky eater. I sprinkled a small amount of one packet and stirred it into his wet food. He got close to his bowl and walked away. There must be a smell that he detected because he didn't taste his food at all. And he loves to eat (when it is his favorite brands and flavors). I now have 29 packets and no use for it. It was worth trying but didn't work out.

Unfortunately a No go

1. The review indicates 45 count. Only have 30 count on the 4 boxes I purchased on 2 orders. Might be just a misprint? I purchased this in hopes it would calm my boy down. Says to allow 6 weeks to see results. Have used for about 9 weeks. Had my fingers crossed this would work at least a little bit but it hasn't. It might work for others, but unfortunately not my maniac boy! Also tried it for sneezing, as vet recommended for another cat but not helped him either. Might help other cats.

This was the miracle I asked for

So my cat, Morris, has FLUTED as a result of anxiety. The vet put him on a prescription that did absolutely nothing to curb his anxiety so I finally decided to go natural. I paired this with Theanine (made for cats and dogs) and WOW he is a completely different cat and it’s only been two weeks. He cames out of hiding and has stayed out. He is playing with all of his toys and follows me around wanting to be held and petted. He can eat out in the open so I no longer have to feed him under the table. Wish I would have tried it sooner.

This worked

I have tried several calming items for my kitty. I sprinkled this on her dry food and mixed it in. She has been eating every bit of the food. And she is calmer and more willing to let me hold her. She is sleeping next to me some nights. All in all, her behavior seems less frantic. I hope this continues!

Works great

Super easy to use. My cats don't seem to mind the taste. I mix it in their wet food almost every day. They have been fighting less and seen to be a little more at ease. I'll continue to try this with them.

Happy with this product!

I’ve been giving this to my cat for about 5 months now, at the recommendation of my vet. The effects are subtle, but I do think it helps with her stress. It mixes in with her wet food really easily and she likes the taste.

No difference

I've been looking for a product to calm my baby girl since she has quite a temper some times. I had my hopes on this product since other products of this brand work so well with my cats. Unfortunately not the case of this product. No change at all.

made a big difference!

I have 2 female cats. Violet is a rescue who had a very abusive background. This included food deprivation and physical abuse as a kitten. So she had a very rough start in life. Sally also a rescue but no abuse. Violet has come a long way but was an over groomer who had removed all the fur from her belly and patches on her back legs. She was very anxious. My Veterinarian recommended trying this before resorting to prescription medication for her. Both cats also barely tolerated each other also. Lots of fights were happening. Anyway I had already started using the Feliway system and started giving them this probiotic in their food. It did take about the six weeks and I started noticing they were not fighting as much and would actually curl up next to each other. After about the second month all of Violet’s fur had grown back! No more over grooming! This works for them. Try it!
