I have a elderly male rat who is missing his front feet and one back foot(probably bumblefoot from before I got him), and he's doing well. He walks on his stumps(on nice soft aspen shred), he's got one or two girls at any time who dote on him, and he feeds himself holding his food or treats in his little stumps like a champ.

He is finally starting to show some age, so I'm watching to see if his quality of life is going down. He's still chubby and doing well though. His name is Gimpy and since he'd been through so much before I got the colony, I figured he deserved a retirement. He even snuggles up with babies(he's fathered two litters!! One was 10 babies!).
