Your cart is empty.For more than a decade, SENTRY has worked side by side with leading pet experts and top universities researching effective ways to help pets lead happier, less stressful lives and to strengthen their bonds with their owners. SENTRY Calming Collar for Cats quickly releases a pheromone through an easy-to-slip-on collar that helps alleviate problem behaviors triggered by travel, thunderstorms, visitors in the home, and even introducing a new cat into the family. SENTRY Calming Collar for Cats has a slip-away buckle that loosens when pressure is applied unexpectedly. IMPORTANT: If your cat has never worn a collar before, please follow these instructions: 1. Apply the collar loosely around their neck and supervise them for 10 minutes. 2. If your cat tolerates the collar, tighten it enough so that you can fit two fingers in between the collar and their neck. 3. Supervise them for 30 minutes. 4. If your cat continues to tolerate the collar, you can leave it on your cat unsupervised.

We recently took in a stray kitten. When she came in to heat, her behavior changed extremely, of course. She walked around meowing and screaming constantly for two days until we received this collar. Put it on her, and within a few hours her behavior completely shifted. She was calm, affectionate and stopped walking around the house at all hours meowing loudly. It was easy to adjust its size, easy to put on our new cat and works very well. The smell is very pleasant and the collar is well made. I can’t recommend this product enough. Thank you for a good night’s sleep!!

PROS: This collar works better than any other anti anxiety alternative I’ve tried. My Furgie is pretty jumpy when it comes to a lot of things, and if there’s new people, new environments, or just periods of heightened anxiety, this collar makes a drastic difference. As it works for 30 days, I can usually sense when the collars effectiveness has ran out, because Furgies anxiety will become more noticeable. I’ve tried other collars and diffusers, with strong funky smells that fill up the room, and they all pale in comparison to SENTRY’s effectiveness.CONS: Before buying this collar I saw lots of safety concerns raised by other pet parents, from choking hazards to causing rashes. I’ve never had an issue with a potential choking, maybe Furgie has a higher IQ (sincerely no offense) but this alone has caused an issue for me. Apparently due to choking concerns, SENTRY made the collar clasp release easier, which Furgie likes to take advantage of in her free time.To combat this, I’ve tried a few methods, and have seen a few on here that look worth trying. HOWEVER: if you’re reading this before purchasing, I’d recommend the first bullet if your cat is indoors and doesn’t ordinarily wear a collar before worrying about devising a makeshift alternative by attaching it to other collars or some other sophisticated workaround.The methods that have worked for me include:• Putting a collar on the cat at least a week or two before putting the SENTRY collar on so the cat gets used to the sensation of having a collar on. Most cats HATE wearing a collar, so this will help with the initial itchiness and scratching your cat will inevitably have to get out of their system. Wait until this phase subsides, the longer the better, as you don’t want to waste your $25 on a collar that sits under your bed in the one spot you can’t reach.• Leaving the collar length a bit longer, so if your cat tries to unhook the collar it takes much more effort and they likely will give up. (Pictures 1&2)• Putting an additional collar on so when your cat scratches the collar they’re scratching the wrong collar and can’t unhinge the clasp. (Pictures 3&4)• A teeny tiny bit of super glue on the clasp before quickly sliding the collar on and letting it dry for a few seconds before the cat has a chance to know what happened.All in all, it’s a 5 star product review for me despite the cons, as it’s the best product in its class and I’ll do anything to make my baby feel more comfortable.

These generally helped my cats adjust to being in a new house, and the smell is pleasant and not overpowering

Had high hopes for these collars as I was desperate to try anything. Cats didn’t seem bothered by them and I personally like the smell. Unfortunately they didn’t seem very effective for my cats (territorial aggression and marking). I wanted to give them a shot but today the collar got loose and was stuck in my cat’s mouth forcing it open. So doesn’t break away as it should. Saw others with the same issue so was always watching for it. Also because it constantly gets loose if you don’t watch it daily this can happen. So for my cats it wasn’t effective and was dangerous but your mileage may vary.

First time bengal owner, desperately trying to find a way to calm down the maniac that is a 4month old kitten, he’s had these for 3 months and I have one in the cupboard still, he’s calm now so I haven’t needed to use it but I’m gunna put it in him for new years tomorrow since he’s terrified of fireworks and this will certainly calm him x 10/10

Usamos em nossa gata que já tem 8 anos e é extremamente medrosa, logo, bastante arisca. Ela estava arranhando nosso filho e muito irritada com os outros gatos da casa após uma mudança de apartamento. Felliway não estava mais adiantando, mas o colar foi um sucesso! Ela está tranquila, menos propensa a passar o dia escondida e sem arranhar ninguém. Está até mais afetuosa. Já comprei o segundo.

The product I received was already opened. Sentry comes packed in a hard plastic wrap, and the collar inside the tin is also separately wrapped. I received a unit with zero wrapping, so who knows how long its been open.
