I'm soooo happy you are taking both special babies...if it works out! There's a terrific (but fast paced) message board at www.handicappedpets.com and many others are caretakers of special needs cats, dogs etc. Bendy a regular poster there put little soft braces on her Bendy's legs when he was tiny and it made a world of difference in helping straighten them out. Beans has a whole other thing going on with him...like my sweet Kirby. Stairs are out of the question for radial aplasia kitties, and more than likely Bethel until you can determine her abilities.
