No clue for a cat that isn't eating that throws up. I have one cat
that will eat too much and then throw that up. I can see him eating
to much or say too fast and then he throws it up. The other one I will
see throw up some but not much. But unless she loses weight I
don't worry about her not eating because I don't see her eating very
often, only because she wants to eat when no one is watching.
