DancesWithCats, in our area, which is temperate, fleas are a problem year around.Even thought we keep our lawn mowed, and treat it for bugs, our neighbor’s don’t. Our vet says that they can piggyback on human clothes, legs, etc and once they get into the house they go for the cat. Fleas are a carrier of tapeworms, and kittens get roundworms from their mama’s milk. They don’t have to be outdoor cats to get fleas and worms, all of my cats are indoor cats. Have not had to deal with fleas since we started on the Frontline.
One year we had a bad flea infestation and had to call pest control out 2 or 3 times to spray, spray, spray and we Frontlined the herd as well for several months in a row. That was AWFUL!! But ... no worms. We’ve just been lucky I guess. Or missed the signs?
