Poor Mama Tootsie... I'm just glad you're taking care of her now! It makes me sad that she's had to have so many litters because of irresponsible owners. I don't know much about those medicines and whether or not they could cause birth defects, but you didn't no, so even if they did it's not your fault. Hopefully the kittens will all be just peachy and the worrying will be for nothing. *Paws crossed and prayers sent your way* Keep us posted!
