My bull will be 4 in September so she'll grow a little bit more but not too much. Those SD retics are the cats meow if you ask me. I was on the verge of getting one before I totally switched directions and got an Olive Python. If I do add another critter it'll most likely be a SD retic. Those paint jobs are amazing! You shouldn't need to feed them anything larger than a large or jumbo rat I'd think.
