I put one of these on one of my particularly nasty cat (to other cats, not me). He seems calmer and spends a lot of time rubbing up against my legs. He got it off after a few days and was back to his nasty self, so I put it back on and he's calmer. He still swats at some of the other cats when they walk by, but he doesn't growl and go after them.

Never get again

By:jb

I'd never get these again! They were worthless. My first one was Feliway but I couldn't find that this time so I tried Sentry. It was like they, my kitties, had nothing on! Smelled like baby powder and nothing else. I gave it a week or two and re-ordered the Nurture Calm -- it seems to be working better. What happened to Feliway?

I have purchased Sentry HC Good Behavior Pheromone Collar for cats twice now and find them excellent to calm my Birman cat. He is an inside cat and they help prevent him spraying inside.

Calming Collar

By:Kristy

Date:January 1, 2013

Pet:Cat

I use this in addition to the calming plugins because I have one female cat who has shown aggressive tendencies towards my older girl. Despite taking my time to introduce them, the new girl would attack the older one who only wanted to be left alone. Time helped reduce the attacks but they hadn't stopped so I added this product. It seems to help improve her demeaner and I do notice that she chases the older cat more as the collar gets to the point (about a month old) that it needs changing. I'm not a big fan of the floral scent, but can accept it if it helps her feel more calm. I would advise opening the collar over a trash can as it has a coating that crumbles when you first unroll it. This isn't a 100% fix, but I do believe it can be another tool in the fight against aggression.

Works Great! I have 4 cats and 2 of them never seem to get along. After we stated using the product, there was less aggression from both of them. What a relief!

Works Great for Stressed-Out Cats

I foster Bengal cats for rescue. I have had success using this pherome collar on a couple of foster cats, when the pherome diffusers weren't enough by themselves. Both of these cats stopped their over-grooming, once they started wearing these collars. After the cats adjusted to their new homes, they no longer needed to wear the collars.

Calm Kitty instantly

I had to wrestle with our cat Gizzy to get the collar on her (She was going out of her mind because of the turmoil of a roommate and her cats moving out.) . Two minutes later she was purring snuggled in my arms. It was like a switch being flipped. The collar lasts a very time and is well worth the price, especially since the effect is so immediate. This is one very calm kitty now, and I am sooo thankful.

I love this product! Bought it in desperation due to an older male cat that kept 'marking' every doorway in my home! Once the collar was put on Timmy stopped marking!!!!! I highly recommend this product if you have a 'marking' cat!

This product not only works but is cost effective. I used to go through the diffuser phermones like water and my cat was not as calm as he is with the collar.

One of my cats had been having some health issues and stopped using the litter box. Even after a number of weeks of medication and his health was better, he still wouldn't use the litter box. The day after I put this collar on him, he started using the box again! I took the collar off after 2 weeks and he hasn't had an accident since!!

One of our cats was misbehaving and sometimes was a bit of a bully to his sister. This has calmed him and actually made him more affectionate.

I bought this at a pet store for $15.99
I did not see it on Entirely Pets web site.
But now I know it's here and $5 dollars less!
My male cat wants out all the time because he sees other cats outside, if I don't let him out he sprays in our house. (He's and indoor cat now and he only goes out with one of us with him)
I have the phermone spray and the plug in, they help but if the plug in runs out and I don't know, he will spray again.
He has had it on 3 days now and seems to be doing better. Now if I could get him to sleep past 5 am I would be even happier!

This collar is really helping my anxious and aggressive foster cat. He seems much calmer and is biting less. I have no idea how long it will work but for now it is working great. :)

Made for a friendlier household!

I can't believe how well these worked. I had 2 male cats (3 yrs old) and had a roommate move in with his 2 yr old male cat. Things were not going well. We tried the plug in pheromone thing but that really didn't seem to do anything. The collars worked so fast! The cats are nicer to new people and each other. They do have a little chemical odor but not too bad. I expected them to hate wearing collars but they don't seem to mind. Although one cat was able to chew it off after a couple weeks, but I may have had it too loose. I would definitely purchase again.

I have a bully, teenage cat that this works great on because he has it on 24/7. The diffusers are great but I can't afford to have one in every room in the house.
