It took a little while, but Odahviing just sort of ignores our cats (we have six). If they are to curious try double sided tape around the base of his viv. We ringed Odahviing's viv base in it. It stops our girls from batting at the glass. They're naturally inquisitive and curious. It's not anything they're doing wrong, per say, it's a behaviour we'd simply like to discourage. It's just the easiest way to do it. If it's uncomfortable to touch something then they just will quit touching it. They actually sell super wide, double sided table at pet stores, usually with the other "no-no" products like the sprays and scent stuff.
