I bought two of these collars for my babies as they are outdoor/indoor cats. One of the cats lost all of his hair and had sores where the collar touched his body. This was not the same for my other cat, however, I removed the collars from both cats. It took 2 months for the hair to grow back on my one baby. The smell of these collars was extremely chemical and strong. I will never buy these collars again.
I had these last year and need 6 of them for this summer, but it's worth it. I flinch at the idea of them having fleas. Besides they're worth keeping comfortable and not throwing scratching fits.
It works and I don't have to worry about fleas so I'm happy, and so are my dogs and cats.Don't have anything for my birds though. They could get fleas too.
