A few weeks ago a pregnant cat showed up on my doorstep. And she's been inside for about 4-5 weeks. She started having discharge for almost an hour then stopped Saturday. She's been contracting on and off since then and I'm worried something may be wrong. She's being really lovey towards my other neutered male cats when before she would hiss and smack at them. But it's been over 9 weeks I'm sure. Also, she started out with her belly equally distributed. Now it's all to her left side.
