This sketch is crude, but please allow me to use it to illustrate one request... Please, please, please pay attention to the foot structure of real animals if you model something like a cat or dog. Up until now, all of the animals available that have "paws" had the foot built while they are standing on it. This resulting 'curve' is totally unnatural and very difficult to work around because it makes it impossible to properly flex the foot into a relaxed state... instead the "heel" of the pad looks like a lump of flesh attached to the joint.

If you can overcome this major problem, I am really looking forward to buying new and improved animals. People are interesting, but animals make a scene.
