And they are easily gotten rid of with a couple of pills, usually. I had one cat with them, briefly, and the Vet treated both of them, to be sure. They can transfer from litter use as well. At the time, my cats were inside cats and did not have fleas. Go figure!

Don't panic, its pretty common! I think the pill costs .09 cents....its the Vet visit that kills your pocketbook! But the pets are worth it!
