I read on here about another chinchilla that was blind. someone reccomended making a fast motion towards the chin, and if they didn't move, they might be blind. well, i tried that on both my chins, waving my hand in front of their faces, zooming my hand towards them and stopping (obviously) before it hit them, but they didnt move. their eyes just seem normal black to me, not cloudy. but when they are out at playtime, and i start to get up and they are at the other end of the pen, they jump around and scurry outa my way. its very strange. they don't bump into anything, and have no problem navigating a newly arranged cage. so, are my chins brave, stupid, or blind?
