So what I ended up doing was going and buying industrial strength velcro. And I just placed the accurite an inch or two above where I had it, so there is little to no room at all between the top of the accurite and the screen cage, so he can't squeeze his way on top of it, and put his weight on it.
But with this stuff, I'm sure it could support his weight, hell, I'm a full grown man, and I'm going to have trouble ripping it off, but I'm not going to risk it. Theres really no room on the ground to put the accurite. So I think this is the best solution.
