My girls Kittens are now 3 weeks old (Persians) so kept indoors, mum was wormed again last week. When do I need to worm the kittens and should I take them to the vets yet to get them checked over. Do I need to do Flea treatments as they are kept indoors, do these battery flea zapper combs work? Lots of questions - sorry ! Im a new mum!
