"This cage is an excellent home for my chinchilla. I provided her with lots of chew toys from the get go, and after 3 months, the only signs of chewing on the cage are a few small nibbles around the upper edge of the food dish.
She really likes to use the ladders as well as jump from level to level. This cage is nicely customizeable - the height of the cage allows for plenty of room to add more platforms, ledges, and toys. I have the large 8 in 1 Snak Shak and a ceramic dust bath in the base of the cage and there's still plenty of room for her to run around. She really loves the leap'n'ledge - I've had no problems with it falling - I just ignored the grooves in the wood and made sure the washers were centered on either side of the cage wires and tightened it up. I plan to add more sleeping and leaping ledges for her to hop around on.
The bottom of the cage is deep, but my chinchilla does manage to kick some hay and shavings out from time to time. If this is a problem for you, I've found just putting a towel or a bit of plastic sheeting that extends a few inches from under the cage makes for pretty easy clean-up - just bundle up the sheet and dump the mess into the trash. As far as ease of cleaning the cage, it is a little involved. I usually hand the chinchilla off to someone else or put her in a travel carrier while I do it. You have to remove the wire portion from the base to clean it, although if you have a shop-vac, that would probably be easier. I also snap the platforms out and clean them, as they have a groove ( a nice addition) for trapping debris so it's less likely to fall out of the cage.
All that aside, if you know your pet is a serious chewer, regardless of the number of toys you provide, you may want to go with a metal bottomed cage. My chinchilla enjoys chewing, but doesn't seem to be big into plastic, unless nothing else is available. However, I know other chins that will happily chew down their entire plastic food dish, and start on the cage with relish, toys or no, so keep the temperament of your chin in mind when shopping for a cage."
