Perhaps something like soundex encoding will let you find the similar sounding cases. I'm not sure that soundex itself will work properly on such short words, but it may be a useful starting point.

soundex retains the first letter so kat & cat will encode differently, and that won't give you what you want directly. But if you encode the first letter as well, then cat & kat would both give 23.
