We delt with huge cats and standard size litter boxes several years ago. Eight indoor cats and two litter boxes with five of them really big cats. Replaced one of the standard boxes with a large plastic tote with a hole cut in one end. The tote is big enough for our biggest ones to get in and have plenty of room to move around and do what they need to. Worked great for us. Hope you get things worked out.
