Can cats use both flea collar and flea spots?

Question

I have 2 cats, one is about 8 years old, and the other is about 5 months old. The kitten has a cat & kitten flea and tick collar, and the 8 year old has a cat flea and tick collar. The collars haven't done much against the fleas, so we bought "OneSpot Treatment for cats and kittens" thats supposed to kill fleas. I want to know if it is safe to use both the collar and the OneSpot treatment? The OneSpot treatment looks like its liquid that you poor on its neck.

Answer 1

None of the vets I've worked for have been in favor of flea collars--they don't believe they're very effective.  I would recommend Frontline or Revolution, and no collar or OTC treatment.

Answer 2

NO!  Cats are highly sensitive to flea products.  Generic brands like "OneSpot" are barely safe anyway, you absolutely do not want to use more than one of them.

The safest way to treat fleas in cats is with veterinary products, like Frontline or Revolution.
