I’ve raised kittens before but I never had a problem with worms until now. I know they have to be at least 3 weeks before they get wormed but the kittens I have now have worms so badly that they are having trouble going to the bathroom. I’m not too sure what to do about it and the vet is not open until Monday. I don’t want to leave it untreated until then. Does anyone know what is safest for kittens that are only a day old?
