I really hate it when my cats kill another animal. Being Buddhist, I can't condone them killing anything, even a mouse. If you read, Chapter 5 of my book, you'll get a sense of what I'm talking about.
Anyway, one of my work colleague's told me his cat brought home a dead PHEASANT! How this can be true, I have no idea. I thought the record was when, sadly, flying squirrels got into my house. I didn't even know it until it was too late. My cat, Stanley, caught 5 flying squirrels in ONE WEEK. Oops. And I just found out they're protected animals! Uh-oh.
