I was just looking over my pregnant girl's belly because it looks like she is losing some hair around the nipples and I saw a flea! The vet did see 2 fleas on her a week ago and suggested I buy a flea comb and comb through her and kill anything I find. So I have been doing that and haven't found anything. And she doesn't seem bothered. Now I'm concerned since I saw it and wasn't able to get it (it was right around her nipple, she started scratching at me for bothering her. What can I do?! I'm obviously not good at finding them with the comb. I really don't want the kittens to get them, I know how dangerous that can be. and the vet said she can't have flea meds. Is there any natural solution to this?
