If I wasn't an hour away, I'd take it.
I had a white rat in college. She was trained to do everything. For being rodents, they're incredibly smart. Easier to train than a dog. I always carried her on my shoulder. When she wanted to use the bathroom, she'd paw my ear. I'd set her down, she'd do her thing, then get back on my shoulder.
If you don't get rid of him/her by tuesday, let me know. I may drive over to pick it up.
