so I’ve been fostering a pregnant mom cat and yesterday she was pacing, meowing, rubbing up on everything. Last night around 9 ET she started to have visible contractions and a little bit of discharge. The contractions continued all night and at one point they were only about 4 second apart. She’s very affectionate and letting me pet her belly I stayed up with her all night and just about an hour ago her contractions stopped. Is this normal? Also, I don’t see any milk discharge from her nipples. Is it always present when labor begins?
