Our cat Southpaw seems to be on a bit of a hunger strike lately. All winter she was a little piggy and ate like crazy as soon as we put the food bowl down. However, as soon as the weather started warming up, we haven't seen her eat hardly at all and she seems to be losing a bit of weight. She seems to be totally normal otherwise--same activity level, if not more perky, not in pain, normal bathroom habits, etc.
(She may be eating at night while we're asleep--we leave a little food out overnight so we can get some sleep. It's gone in the morning, but it could be our other cat eating it as well.)
Normal? Would you worry?
