Sounds to me that other then the floppy ears (which a breed already has) she is trying to create a breed based on non-physical charatersists. Most breeds have some defining physical difference. No hair, no tail, ancestors of the Leopard cat, big furry mane, flat face, long face. And in my hypothetical new breed, more toes. I would think it would be very hard for a judge to rate a cat in a cat show based on how 'dog-like' it acts.
