COSYWORLD Flea and Tick Collar - Adjustable & Waterproof Flea and Tick Control Collar (one Pack)

First of all, the reviews for this product are for shampoo and car seat covers?? Second. These flea collars do NOT work. I am not able to give my cats topical treatment because they get very fussy when I try and sometimes lash out with tooth and claw. So I bathe them and put collars on them. Usually any flea collar I use works great. Not these ones. After four weeks of continual wear + weekly baths, my boys are still covered in fleas. Spraying the house only does so much when the fleas are multiplying on my cats. Proof that these don’t work, they are covered in my cats’ blood where the fleas bit right under the collar.

I'm so surprised to come back to this item and see such bad reviews. My two male cats have been wearing these collars for 4 months now with no side effects other than LESS FLEAS!! You need to Brush your cats daily and vacuum often. If you have carpet put down diatomaceous earth for a few days then vacuum. Do that once a month. The hot light over a soapy plate at night method catches a lot too. Keep at it and you can beat it. I thought I never could but I did. Don't be afraid of this product, be afraid of the chemical collars.

I purchased this item thinking it would be safe for my fur babies but this contain peppermint,eucalyptus, and pine essential oils all of which a very harmful for cats. These are fine for humans but can make your cats sick to the point of death. Please so not purchase!!!!

My kitty wore this for several days. When I checked the flea were alive and well underneath the collar.

Fleas are literally hiding under the collar. Doesn’t work at all. Waste of my money.

It has been on our cat now for over two months and still working.

Does not work!

My cat is an indoor/outdoor cat and this is the second tick we have found in close proximity to his flea and tick collar. I do not recommend!!
