i just whitnessed my 1 1/2 year old cham budweiser fall from nearly the top of his 4 foot cage as he was climbing on the cage and tree. he did not seem hurt because he started to climb right back up. i took a good look at his claws and noticed his back feet the inside of his toes did not have nails. im not sure if they fell off from all the climbing or w.e. any thoughts ?
