Comfort Zone Cat Calming Collar Value Pack: 4 30-Day Calming Collars for 120 Days of Calm; Cat Pheromones Help Anxiety, Reduce Stress, Urine Marking, Scratching; Indoor or Outdoor Cats; Long-Lasting

Calmed down my cat completely, who now no longer bullies the other cats or attacks us out of frustration. Spends her time eating, sleeping and chilling with the other cats (who she never got along with before)

These calming collars help keep our newest rescue cat from picking fights with his new siblings. He was a bit of a bully to our other cats when he first arrived. The collar, in combination with pheromone plug in products seems to help keep the peace in our house. We can tell when the calming effect is wearing off because he starts to stalk the other cats and picks fights. I only wish the effects lasted longer because this product is expensive.

As coleiras estão sendo utilizadas em um gato macho não castrado de três anos que vive em um apartamento sem outros animais.O felino (acredita-se que) estava com cistite causada por estresse e urinando por toda a casa, menos nas caixas de areia.A regressão dos sintomas foi observada após duas semanas de uso da coleira, e a partir da terceira semana o gato parou de urinar fora das caixas de areia completamente.A efetividade da coleira dura aproximadamente um mês e meio.Além da utilização da coleira, é necessário implementar enriquecimento ambiental vertical, adicionar mais caixas de areia e realizar brincadeiras e atividades diárias para um resultado mais eficaz.

We have a female and male cat both fixed. Male is so aggressive with female constantly on her and after her. Put the collar on him and he is way more mellow. He still bugs her but not to the degree that he does when he doesn't have collar on. He is relentless. Definitely worth the money in our case.

My kitty wore this collar with 2-3 finger spacing. I had it a little loose as I didn’t want her fur to get squashed however after a month of wear, one day I took it off and found fur around her neck to be patchy. It’s not just divided fur but patches of fur gone. It can’t be friction as I had the collar loosely fitted. My only guess is that she was allergic to it. Use with caution!

I am sharing this because of a review I read about an established male aggressor/bully and a new younger female cat that gave me hope, in case this helps anyone.I have a very rambunctious male cat who grew up a single kitten and with dogs. He had single kitten syndrome and could become aggressive with the dogs and with people (never learned that biting and scratching hurts from playing with other kittens). Earlier this year I adopted a younger female cat so he would have a friend, because we no longer lived with dogs and he needed a playmate. I introduced them slowly and followed Jackson Galaxy’s tips for introducing cats. I bought these for my male cat to wear because it wasn’t going well and he would be very rough and aggressive with the new cat who is very laid back. This stage can be frustrating, scary and feel hopeless but it’s super important to avoid the “stare down” and to avoid letting them fight (watch Jackson Galaxy’s YouTube videos). I couldn’t be certain if the collars worked at the time but I was willing to try, so male cat wore one indefinitely. We did the intro and our visits got longer and longer after 6-8 weeks they could coexist and play and I could leave them alone at home when I left without fear of male cat hurting new baby girl cat. They became friends.Fast forward to moving to a new apartment 3.5 months after adopting new kitty. Male cat was wearing one of these that he had had on for a month or so. No way did I think it was still working if it ever did so I removed it after being in the place for 2 weeks. The cats had been playing like they always did (play wrestling but no ears back or anything more than playful biting etc.) and seemed to be adjusting fine. Then over the next week or so I seemed to have to start breaking them up. My male cat was becoming more frequently aggressive to the younger female cat. It got to the point where every single time he saw her he would put his ears back, stare her down from a distance before launching at her, body slamming her, biting and kicking before I realized they were no longer having positive interactions and my younger cat was becoming afraid of him. I said enough is enough and I separated them and decided I would reintroduce them like Jackson Galaxy recommends. I separated them for 1 full day and got a second litter box again. Admittedly I thought I could get away with only 1 for a short time while settling into the new place but this was clearly not a good idea. In the meantime I put the old calming collar back on my male cat and ordered new ones for overnight shipping.Male cat has had a new collar on for 36 hours and they are back to coexisting and playing without having to be broken up. No signs of actual aggression from male cat. He is playful again without hurting the young female.I am so relieved that my little cat isn’t getting bullied anymore and that it happened somewhat quickly. Although I can’t say the collar alone would have helped, I am a believer and I will continue to dress my male cat in this collar so long as he is a whackadoodle. But I will also remember to respect his territorial needs.Long story short, do NOT skip the basics like proper introductions, adequate litter box territory, vertical spaces to climb, playtime, ruling out health issues etc. and expect this to work. I can see now that the stress of adjusting to new territory as well as only having 1 litter box posed a problem.I also just can’t help but wonder if the collar was still releasing pheromones after 1 month, because of the increase in aggression I believe that happened in the week my male cat had the old collar off. Anyway, I am happy to be on the other side of the problem!
