So I just discovered that both of my cats have fleas in their body. Whats the best way to treat this? SHould I take them to the vet or just buy a flea spray at a store?

Also, will they be able to get on me?

Advantage or w.e

green palmolive dish soap
get the cat wet, suds them up (be generous)
10 minutes
???

Use fire.

Bathe them with a flea be gone shampoo that is approved by a vet and use follow up treatments for flea control (such as Advantage).

And yes, the fleas can get on you.

i looked this shit up...

thats legit advice... to figure

You also must clean the places where your cats stay, because probably you will find flea there too.

I use frontline on mine wen it had fleas, is very effective and each treatment last for a month

have sex with them, fleas can't stand the stench of success
