Hello everyone, I took in a pregnant mom a month ago who was going to be put to sleep. She is a sweetheart but lately she's chasing my other two cats around and the hissing is crazy! No one has been hurt but I'm wondering if this is normal. My other girls were spayed as babies and no other fosters I've helped had this issue. Granted this is my first pregnant cat. She's starting to really fill out now, looks like she swallowed an orange in her lower belly. She also started losing hair around her nipples but not tons. She is medium hair so extra fluffy on her belly. Any ideas??? Thanks in advance for the help.
