Cat

We have two cats: Riska, the thin one, and Burka, the fat one. Burka is always looking for more food. And as any cat sometimes they do throw up. I come down to the kitchen, and Burka is meowing and meowing and meowing.
Me: Did you feed Burka?
Gwen: Yes we did
Me: Why is she meowing then?
Gwen: She wants more so that she can throw up
