Really seems to be calming my Siamese
This has quite a strong smell and my Siamese scratches around his neck frequently so it might ‘irritate’ him occasionally. But he was stress peeing daily, sometimes twice on front door mat, for a few months and this collar (plus calming tablets from Vet) has reduced his stress and thus, peeing although we have had a couple of hiccups which is disappointing after nearly 3 weeks pee free…. He was on the tablets before I bought collar which Vet recommended as tablets alone wasn’t effective - collar + tablets is definitely a game changer. Stress peeing makes owners stressful which in turn stresses cat more so eliminating this habit is essential and this collar together with vet tablets definitely has improved situation. Bought a second one and hoping after another month we can discontinue wearing it as habit broken.. might need a third… we shall see!

Expensive, but consistently works, does not have a strong smell. Buckle is poor.
I’m reviewing again after a few years of not using this product. I have a very highly strung cat (the brown one). Lots of anxiety symptoms like PICA and aggressive tendencies to our other cat. It’s recently been bad (eating and digesting our mattress!), and he’s been full on aggressive with cat number 2 for about 6 months. I’d finally had enough and purchased this brand of collar (the original US version - and yes I struggled with purchasing an American product and supporting their economy at such political times, but it’s the best one! -I’ve tried the cheaper ones). Instantly our problem cat was calmer, cuddling and purring with us within 20 minutes, and no fighting with our other cat… in fact look at this photo 48 hours later! It’s worth the extortionate cost. It’s smells gently of sweets (candy), the smell is not over powering like the cheap lavender ones. The down fall is the collar ‘buckle’ - it’s terrible, if my cat was absolutely determined he would definitely be able to get it off by struggling with it. I’m thinking of making my own securement system. But for now he has behaved and kept it on.

These smell soooo good!
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

10/10 recommend!!
Worked amazing for my aggressive cat. Before he would chase the other two cats around and after putting the Sentry Behavior and Calming Collar on him, he’s relaxed, no more chasing behavior and gets along well with the other cats. 10/10 recommended.

Sensacional
Tenho muitos gatos, e muitas vezes as brigas são certas, principalmente na lua cheia. Essas são as únicas coleiras que funcionaram de verdade e duram bem mais que um mês . Produto sensacional, podem comprar sem medo. Apenas um dos gatos teve uma leve irritação na pele. Mas ainda assim, recomendo. Lamentável que a taxa de importação para o Brasil eleve tanto o preço.

Calms my cat and me too 😌
Starts working right away on my cat. I buy this collar when i have to leave my cat whenever i go on vacation. That way when the cat sitter checks on her she’s calm. I’ve bought the treats too and she likes them. The collar does have a significantly stronger medicated lavender-ish smell right of the box, but then subsides. Makes me and my Tiki feel calmer 😽

Sin pleitos desde hace 3 semanas
Mis gatos nachos tienden a pelear, pero desde que traen el collar 0 incidentes.. el que es más miedoso está más cercano y se deja acariciar.. muy contenta.. llevan 3 semanas voy a ver cuánto más dura esta belleza de realidad, creo que en quedar unos 10 días, ojalá se extienda…
