So right now I have my cavy Xander in a 1.5x3ft aquarium style tank. I've been doing some digging into getting him a new, larger, habitat, and have come across a few possibilities (I found an 8sqft cage within my price range yay). The only problem is, it looks like a lot of cavy cages do not come with covers for them. Right now I have a wire mesh cover on his tank. Does the habitat need a cover? Will he make an escape attempt if there isn't a cover? Thanks in advance for your advice.
