Starrkey chewed my hair for the first time the other day! With his new (another) buff cage I've been able to customise a normally 4 tierd level cage so it is a top layer with a ladder which i have as his eating/housing area, then what would be the bottom 3 levels i have filled with wood ledges. This however has left me with two random cage doors, which means i can sit by his cage whilst he's bouncing about and shove my whole arm in all the way and use it to be a ledge.
He has started clambering up me then discovered my hair too and started chewing that...theres nothing he won't chew!
