Sick cat

My cat Athena is sick again. She puked up her food yesterday around noon and I haven't given her any food since, though she rubs against the fridge and looks at my with huge eyes. This cat has an appetite that won't quit, even when she can't keep it down!Since then she's thrown up several times, just small bits of liquid. The last time that I was aware of was at about 2:00 in the morning. I have a very long day teaching at Earlham, but I hate to leave her all day like this. At least she still seems very lively, not acting sick or sluggish at all. I will have only a little bit of time to check on her before having to dash off to my writing class.If I need to take her to the Vet for another injection, I can do that tomorrow afternoon. Poor kitty!
