Well, this she is 7 weeks and is about a pound. But, her mother was extremely small ( she came from my brothers cat), who was quite young. The mother is 8 months old right now and is about 5 or 6 pounds at the most I would guess.
As far as the vet, she has an appt in 2 weeks for a check up. I did call, and they said as long as she is eating and using the litter box w/ no problems I shouldn't be concerned and it can wait till her check up.
I was just trying to get a feel for a ballpark figure on what would be normal. Thanks!
