Cat thinks she's a retriever dog
She love to retrieve her toy mouse like its the real thing. The more you tell her to kill it, the more she will continue to fight with it, pound it, toss it up in the air. Then she will bring it back and put it in your lap for a reward, pat or to play again. She has even once tossed it in my fish tank to attract the fish so she can grab one of my large fishes.
