So I'm wanting to get my girls some toys for Christmas. My question is simple- what? They've had wood chews before, but it wasn't a big hit (they just ended up chewing the tunnels in their cage instead). And they've had the little jingly cat balls, but only one of them REALLY loves them. I honestly feel really bad- I want them to have a lot to play with in their cage, but I feel like I'm running out of ideas.
