Rehoming cats

I have 2 female cats that I need to rehome. My daughter has developed a severe allergy to them and we have made the tough decision to rehome them. Lulu is 3 (brown) Moomoo is 2 (black and white). We will give everything we have for them. Litter, food, bowls and an automatic litter box. Very good with kids. I am asking a rehoming fee to make sure they do go a good home.
