I need some advice on toys for my girls. I need something that can be chewed on because Lucy tries to chew on everything, but I also need something a little bigger because Daisy is bigger than Lucy. Daisy got stuck in the last tunnel thing I had that Lucy was able to chew on. Any suggestions? All that's in their cage now is two hideys and a hay rack. They need more to do, but I am at a loss on how to accommodate both of them.
