well, i ain't seen no big bouncy tiddies yet and in my belief anyway the main reason why the furries come into existence is that furry things with lotta curves and massive tits during puberty and you sexual awakening resulted in weird fetished, confused boners and in the case of those bound to be perverts, yiffing and fur suits.
Or we find the concept of cute fluffy things doing people stuff fascinating.
Your point is valid, just pointing out it other scenarios. The one you described is my case, but I've seen others who are weird.
Not like Disney, Marvel, DC, and pretty much every other childrens entertainment company hasn't been doing anthropomorphic characters for the past 50 years or anything silly like that...
Yes, they can move their ears.
They don't have bone in their ears, but there are muscles attached that move them, just like horses, cats, dogs and so on can move their ears, and some humans kinda wiggle theirs.
