I did some research, but I'm a bit concerned about the methods recommended, namely diatomaceous earth and giving the kittens a bath. I believe the kittens are too young for a bath since they don't have their eyes open, they are only 11-12 days old.
I called the local pet shop and they recommended cedar oil. They said it is safe for kittens and the nursing mother while she is lactating. Is the pet shop's claim that cedar oil is safe for kittens true?
If not, please let me know what I can do to treat the kittens! They are very young and vulnerable.
