I have 4 INDOOR cats. The first two arrived with fleas but I'd treated them before they even came in the house and I bathed them.
We've had them 8 months ish.
They're treated monthly, they don't go outside. We have no other pets.
We had an issue with lice a few months ago that took ages to get rid of becuase I thought they were fleas and was using the wrong stuff. Got the right stuff, lice were gone.
Less than a month later I see a definite flea on one of their faces. Treat them all. We took them with us to a renovation were doing and treated the whole house with the brutal bug stuff. There should be no fleas in the house or on the cats. It's been 2 weeks since we got back and they've all got flea dirt on them.
I haven't seen a flea yet but they're all fluffy and wriggly but there is definite flea dirt on them all.
What the hell is happening?!
