Unless you do something about her, you are going to be more stressed out when she has kittens and brings those to you for help. She's had a tough time, coped with losing part of her leg, she deserves a helping hand. You could apply to IMOM for help in cleaning up her leg, and the local shelter will spay her at a lower cost. If she has to live in the barn until you buy a bigger house, she'll be in a much better position to survive that experience if spayed and checked out by a vet. A styrofoam house inside a barn with hay will give her the warmth and shelter she needs.

She is very pretty and appealing.
