I think that could work! Because I can also add some branches to cushion the back of the cup in case it would want to tilt forward. Hummm...I'm ordering it. That is fantastic! Thank you!
I'll post some photos soon of how I did drill holes in some of my cage perches to slip toys through it. Someone here on the forum shared that idea. This is so neat because you can use the lower unused part of the cage so much more when the toys can dangle from the perch. Francis goes down to play there more now. Oh! I am excited! Thank you! Still loving our sprouts every day too!
