I am a bad rat mom

This morning I woke up, looked around all groggy, and then realized that Clive's cage door was open. He was not inside. I remembered falling asleep while he was crawling around. He was no where on the bed, and my apartment is still quite a bit messy. Added to this the sudden realization that there was Warfarin in the apartment for the mice.
I was in a state of distress when I found him curled up, happily sleeping in a garbage bag. Rats will be rats, after all. I picked him up and kissed him and said "I'll never lose you again!"
He's such an old rat, I'm amazed at his determination to keep living. It's inspiring.
