Wow, he is just beautiful...what a darling little thing! Nibbler was right, Lilspaz is on the forum and hopefully she will see your post and give you some good advice on this. Wish I had some advice to give on wild rats! For now, of course, keeping him safe, warm and fed is the best you can do. I know my natural instinct would be to turn him into my lil baby and take care of him always, but I know there are issues with wild rats, so I can't let my "aww" feelings cloud my judgement on the best thing for the little guy. At least for now, he is helpless and needs a bit of TLC. Good luck to you. He really is darling.
