OK, so maybe this little guy isn't exactly orphaned. More like some big meany (me) took it away from its family at the pet store to feed it to my snake. Unfortunately my snake had a different idea and didn't eat.
I'd like to keep this guy alive for a few days until I can offer it to the snake again. Partly just don't want the money wasted but also while I'm ok with feeding mice to the snake, I feel bad about a baby mouse slowly dying for no reason.
What can I do for it?
