Over the last week, 10 month old kitten is pooping less frequently and is very fussy about eating. We're 98% sure that her fussiness is not from illness but a teenage rebellion! Because of her age, she's also slowing down and expelling less energy than she did as a kitten. She's a small thing, only 4.6 pounds, so she doesn't really eat much anyways. Because of her fussiness, she's been eating less than normal, though. Any advice on what the problem could be? Also, how can we overcome her hunger strikes?
