Review: Plain and simple, it works. - This collar works for my inside outside cat Ziggy. This collar is Ziggy approved (see picture). She is a long hair cat and the fleas were on her in one day outside. I put this collar on her and the fleas were dying then gone within 3 days. Never once saw a tick on her and my wife and I check her often. We live in a wooded area and fleas and ticks are a real issue. When we took her to the vet for her maintenance shots the vet scoffed at this collar saying none of them work. I don't care if he's a doctor he's still wrong and wrong is wrong. Buy this collar!
Review: you won't be disappointed - Virtually no ticks this year. Very pleased. My cats don't mind these collars at all. No smell or gross liquid. Highly recommended, you won't be disappointed

Virtually no ticks this year. Very pleased. My cats don't mind these collars at all. No smell or gross liquid. Highly recommended, you won't be disappointed

### ⭐⭐⭐⭐ Toon soon to tell...
*by J***. on August 3, 2024*

I literally just received these and while slightly familiar with the features of this collar, i done messed up during the activation. I broke one within seconds at the 'BREAKAWAY while stretching it as per the directions, which should include a emphasis to be careful of that point of the collar. Hartz, please for the sake of others, update your instructions. Otherwise, having just appling the collar i have no further input, but have had success with Hartz products in the past. If i feel inclined will update this review with better feedback on its effectiveness.
