Oscar, the gray cat on the table. Charlie may be bigger and stronger but Oscar is just too damn mean!
I should explain that Charlie just sits where Oscar is just to annoy her. And Oscar is so disagreeable with everyone and everything that she just can't not pay attention to him. She'll sit there hissing while Charlie looks around at everything except her.
Finally it just gets too much for Oscar and she'll fly off the table, chair, couch, stairs, etc and attack Charlies. Fur will fly (always Charlie's) and she'll walk away the winner. And it happens over and over again. Why? Good question. We just don't know.
