Thanks all! I was just doing some cage tidying up and Malachi is celebrating his birthday in grand style (aka lazing about under a layer of newspaper with his hide stuck on top...his new fashion statement). I had to move him to check his tub and freshen his water and got a typical Malachi "hello"...a low, long toned hiss LOL. He never bothers to strike, he just likes to complain a bit if you move him from his comfy spot.
Tomorrow is feeding night so he'll get an extra chubby weanling rat for his "birthday" lol
