I had rats years ago, but haven't in a while. My last mouse recently died, and I think im ready to get another pair of rats! I have my girl's old cage in storage, it says on the cage that it's a critter nation model 162, does that make sense? I don't really know. But anyways, when my old rat kipper died, I didn't really bother to clean the cage other than a quick wipe-down. So now, looking at the cage, there was some urine or something (eww I know) on the bars that dried. It isn't really rusty, because the metal is coated with something, but it is definitely dirty. Is there some way to clean the cage now? I've tried with a paper towel and water, but the stuff is really dried on there. Also, my old rats liked to chew the trays that lined the bottom and the shelves, and they were pretty destroyed, so I had to throw those away. Is there somewhere that I can replace these? I really don't want to buy a new cage, they are so expensive, so any suggestions are appreciated!
