Sergeant's Guardian Pro Flea & Tick Cat Collar, 1 Count

I would give this a zero if I could. Not effective. Very disappointed.

Since I'm not the 1 wearing it. That being said it seems to be working fine. My cat spends alot of time outside. And as far as I know hasn't brought in any fleas or other such pests. Which was a problem with 2 of the houses in the circle.

I bought two of these and one of my cats had a bald ring spot around her neck, I suppose she's allergic to the active ingredient, this completely understandable, they're just like humans I'm allergic to ibuprofen so I know I can't take it, now I know my cat is allergic to this ingredient so I won't buy it for her anymore, the boy is doing just fine, no adverse reaction whatsoever.

did not prevent, slow down, or do anything for fleas. I personally would never buy again.

My cats are indoors, but I moved from a house to a pet friendly apt. Got these as a precaution, and also because mosquito season (i sit with them on a balcony). One cat loves to cuddle, and right next to my face all the time. The collar has a strong odor, that isn't exactly unpleasant, but is annoying, and sticks to the fabric. The other cat didn't like the feel of the ‘clasp’ to the point where he was scratching out tufts of fur after less than a day (even when i rotated it). Removed it and he didn't scratch anymore, and he hasn't reacted to the other cat’s collar. Can’t give the effectiveness of the product a review due to how short term they were used, which is why i only put 3 star.

We have an outside cat & this collar works just like it says for the entire time. A wonderful product well worth the price!

Cats seem to respond well.

This is the second year I have bought this kind for my cat and we have never had a flea problem. Way better than spending a fortune on the expensive brands.
