lice....I was waiting for them because the day care had some a few months ago. One thing I found is that during head lice season *lol* a lot of mums come into the vet clinic & buy flea spray....apparently it works a treat and only takes one treatment, but its pretty toxic stuff... :-k don't think I would be using it....one of the vets tried it after she got lice from sky diving helmuts & it worked within a few hours. Luckily Matilda hasn't gotten it yet *fingers crossed*
