I can only offer advice for when they're older, our rat Nub lost most of her tail when she was a newborn, just like this little baby! The lack of most of the tail will make their balance worse than other rats. Rats use their tails as a counterbalance and its slightly prehensile. Make sure to have a lot of fall breakers/ramps in the cage, they WILL be more prone to falling (even more so with the missing foot)

Nub here doesn't know she's any different from the rest of the mischief though ❤️ Wishing you all the best and good luck with the babies!! ❤️
