i don't have an answer to how much you should feel but your post caught my eye... i switched barbie to wellness 5 months ago and at the vet she weighed 6 lbs even... now when i took her 3 days ago she was 5 lbs 9oz.............. i was SCHOCKED but the vet wasn't concerned she said it was still a healthy weight as long as she maintained it. just a little weird
