I have the Zoo Med, 40 gallon front open terrarium. The lid has a screen. My cat loves to sit on top, but his weight is causing the screen to break.

Is there a replacement lid that's not a screen, maybe a plexi-glass? Or a cover I can get so he can't sit on the lid at all?

I already looked at terrarium stackers, I would have to make a lid for the stacker so he doesn't still just get onto the lid, and they're kinda expensive. I already know scat mat won't work because it hasn't deterred my cat in the past. He also doesn't care about foil or cling wrap.

My hoggie is currently burrowed, I just moved him to the new rank last week so he is still acclimating. But I need to solve this before he comes out to explore!
