So, I just noticed that my cat, Diesel, had blood in her ear and a mark on her back. Then, a few minutes later she began throwing up A LOT. I don't know what happened. I was just playing with her less than an hour ago. It looks like she was attacked, but I don't know what would atttack her. She's an inside cat. PLEASE if you have any idea what this could be post. I'd really appreciate it.
