Hartz One Spot Treatment

I tried this before I used Advantage Plus which I got from my vet. This product doesn't work the greatest. I also wouldn't recommend it for older cats as it may make them very ill. It may kill some fleas but isn't long lasting. Not worth the risk in my opinion.

Pros: works if infestation isn't bad

Cons: may make cats sick

Hartz flea treatments contain harmful chemicals that have been known to be dangerous to many pets. My cat already has minor skin problems, so I won't use this product on him. However, I wouldn't recommend it for use on any animal. It has had harmful and dangerous affects on a number of pets.

Pros: cheap and easy

Cons: Dangerous and ineffective
