just picked up a pregnant cat two days ago from our local shelter. She actually just raised a litter and managed to get pregnant again. She’s about two weeks away from delivery and we’ve noticed she’s sleeping a lot more and eating less than she was on the first day. She’s fully switched over to kitten food and was eating 2 cans a day and now she’s eating about 3/4-1 can a day. Is this normal? Should I be concerned
