My 1 year old cat who I had since a kitten, recently found out she had heart problems, she had water on her lungs which she takes tablets for, my vets said because of her heart if she got pregnant she'd die but her kittens would survive, I not long found out she's pregnant because her nipples, belly and the way she's walking, I'm worried sick, I love her and don't want her to die, she haven't had her lung tablets for 3-4 months but she's fine, better than ever despite the vets saying she needs her tablets otherwise she'll die, my vets are a charity so not exactly vet experts, will my baby girl survive?
