Review on 🕶️ Hartz Ultra Guard Reflecting Flea & Tick Cat Collar Review: A Reliable and Stylish White Collar for Ultimate Protection - 1 Each by Smriti Pearson

For the most part it was terrible. They smelled awful and the cats hated them. I was willing to sacrifice a little if it meant no fleas. And there were no fleas for about a day. And then it seemed that the collars weren't there, apart from the horrible smell. The cats wore these collars for about a month and the smell never went away which I expected because it had to get rid of the fleas somehow but after a day or two the fleas didn't seem to care. Not even the collar bothered her. I saw her crawling over my cat from above and below. I don't know if I have a few glitches or if I have super fleas but overall I was very disappointed with this product.
