Gorilla glue question

Thanks for the suggestions but my cat don't mind either. I tried. I had one tank with just plants in it, tried the tape on the edges, he just jumped over it...So I put it around the edges and across the middle of the top. He still just jumped over it. So I tried covering the whole top, to no avail rotfl. I found him curled up on the tape taking a "cat" nap :please:

Same with tin foil. Nope he don't care what he walks on or sleeps on.

Thanks for the suggestions though :)
I'll just try the plexi glass and see what happens, on a trial tank I have setting here not the one with Dori in it!

Well....this next solution is not the nicest solution... But if the plexi bends, I've used a boat horn to train the dogs. I only use it for issues that can cause harm to a pet or person. But if you happened to blow the horn every time they do the thing.... Pretty soon the thing never happens again.

That in mind.... I hope the plexi works!!
