Especially with a warm light on top, my cats love to sleep on my vivariums. A spray bottle has mostly taught the cats not to harass the frogs. Front opening tanks with lids made out of perforated sheet metal for ventilation are my solution to withstand the sleeping. I believe that exo-terra makes a low and long front opening tank that might be suitable.

A shelf system would work as well, but I'd still want front opening tanks, and you may need a small fan or two to improve circulation especially if you have an enclosed light source.
