Hey guys. I've never had a pregnant cat before and I may be overreacting but I don't want to screw up: On February 1st, I took in a stray and took her to the vet, where the vet took an x-ray and said their skeletal systems were just beginning to form. She said the cat would give birth in approx. 20 days. Well, she's waaaaay overdue. I called the vet and she said not to worry, and to call back if she started bleeding or acting funny. The cat seems fine, and she's HUGE. But I just don't feel right about the while thing. Should I take her to a different vet for another opinion or just do what my vet said? What would you guys do?
