The screen top i have is the kind that is hinged length wise.. unfortunately the hinges rusted...and now its separated.
the kitties like to sit on top of the screen so its not good that its not completely closed. For the time being I have taped a plastic lid from an under bed box to the outside of the tank so that if and when they sit up there it wont sag in the middle and create an opening. if that makes sense.

Now my question is...is there a hinged screen top that wont rust!!??
and does anyone think the hinged ones would be more supportive of the kitties sitting on top of the tank? do we think a hinged screen top is stronger than say, one that is the metal mesh the whole way? or not? cus the hinge parts I guess are not that sturdy?
you probably became a little dumber after reading this im sorry. LOL
