great cage set-up

I would love to have this cage http://www.petsmart.com/product/index.jsp?productId=3402796 the Critter Nation for the rescued pets. It can house rats, sugar gliders, degus, chinchillas and even ferrets. The problem with many of the larger cages I have is the bar spacing. The bar spacing is too far apart, most of the little ones can slip through and escape like the rats. This is such a roomy cage that is easy to clean :) Maybe for my Christmas wish list. Ray ( the hubby) says we already have enough extra cages. But he doesn't understand the need for larger cages for their happiness, and that most large cages have bar spacing that isn't adequate for the smaller guys. It is pricey too. Maybe someday... I love to treat the rescues with the very best :)
