Ive had my uromastyx for nine years but now hes suddenly acting weird. Now every time I take him out of his cage he pees on me or on the floor. In the nine years Ive had him he only peed outside his cage 2 times up until recently. Also under his neck his scales have turned a whitish gray. He just shed so thats not the reason for the discoloration. Any thing you can think of that would explain these symptoms?
