There must be at least 5 different chew toys in Tyra's cage but no, the side of thecage is much more fun...espescially at 5 o clock in the morning.
why is she doing this?
As for Twiggy in the other cage, she's decided that the day time is a good time to be awake, and being nocturnal isn't fun...
they're both very strange, and they snore ^o^ it's cute
