Hello, I recently brought in a stray cat.. she was confirmed by the vet to be pregnant just not sure how far along she is. She was far enough along to see fetuses on X-ray. I’m just having trouble telling when she might be due, her nipples are bald and big, she scratches at her litter box, her appetite is off and on.. any help would be great, if you can tell me if she might be close as well!
