My oldest cat has been sick for the past week.
First she was vomiting, and then she wouldn't eat. She has perked up a bit now energy wise but she's still not eating.
She went to the vet on friday but they couldn't pinpoint anything wrong.
I've noticed that she doesn't want to chew on dry food, so I reckon they missed something in her mouth (which they briefly looked at), an ulcer or tooth abcess or something.
