This will keep everyone out of the thread.*Bob opens the cage door....*
**Suddenly a wild judgmental human faced cat appears
Aww lovely, he/she is blowing bubbles out of his/her nose! Is that your dog, Bob?
I though real cat toes at first, but I think those might be second paws growing out. I didn't look any more than that. So technically, no toes.
I imagine that would help out a lot for cross unders on scales.
Yeah, but their stretch is abysmal.
In fact I have given a few piano lessons to both cats and dogs recently (the owners find that very entertaining). The limited span and lack of finger independence really does present a problem for both. But cats have a much more flexible general posture than dogs, it's really difficult for dogs even to sit and play both hands. Dogs also have these hard nails that do not retract. So I'd say the changes of finding a cat virtuoso are much higher. I wonder if they would do better starting with a small keyed toy piano than a real one though...
The fact that you made such a detailed analysis of the situation makes me wonder as to your level of sanity...
