I’ve owned kitty cats since I was just a little squid myself. We’ve never had to de-worm. I’ve never had a cat with worms. I can’t understand how you’d be experiencing this phenomenon. You mean, they ate something disgusting and wild (a nice mouse mousse?) and picked up worms from it? Ick. Glad I keep my herd in.
Three of my four cats are former rescues / strays, and all needed deworming. There’s a lot of yuck in the world.
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.
