Just wondering if anyone has had this experience. My females teets are getting big. She had puppies 5 months ago, and they had almost gone back to normal up until she went into estrus. They usually get bigger after a heat cycle then go back down. She was in heat about 4 weeks ago they never really got big until now. I doubt it's a fake pregnancy seeing as it's been a while now and it usually happens right after. What I'm wondering is... I brought a kitten home it's about 5 weeks and I caught it nursing on her. Has anyone else seen this happen, where maybe it's instinct to produce milk from something nursing?
