I just got two 6-week old kittens a week ago. (Guess that would make them 7 weeks now...) One of them has been begging for food every time we are eating, and has been eating her dry food until her belly is swollen. First visit to vet isn't for another week and I am worried that something is wrong with this little one. I believe this one was the runt of the litter, and she is much smaller than her sister. Is it normal for her to be eating until her belly is so swollen? Please help, I've never had any pets before.
