Aquarium topper

I think by the time u buy a cage topper then u should buy or make a totally new cage. I made a new cage out of hardware cloth and use my old aqauriums for pregnancies, qaurantines, and any other reason for them to not be able to be in the new cage. If you juss want a cage topper id suggest adding cloth (that u can throw away) in the sides and corners to kind of mask the pee on glass issue. I hope this helps all glass pee issues lol -Josh
