it's a freaking rodent. the bottom of the food chain, why would you cry about this?
Little jimmy, let me educate you on... Pets. Pets are animals that we humans adopt into our family and love and care for. Some have important traits that can help with daily lives, and others are either useless or pains in the asses... Now, when a pet dies, something you've been feeding, nursing, and loving after all these years, just loving blew up into what I'm guessing are chunks. I'm pretty sure you'd be sad.
So that's all you need to know about pets. Now stop being a douche, cause any day now your dog/cat/etc might just explodes, leaving chunks of itself everywhere, that you have to clean up.
