Congrats on the soon to be new addition! You'll have to post some pics when he/she arrives.
I love the Hissers; regular roaches creep me out. I want to get a Praying Mantis someday, too, though they don't live for too long.
I love my geckos, but I have to put them on a diet. My male, Mika, is making me feel super guilty about it, too.
Kamani, my tarantula, is very cool. She is currently munching on a cricket as I type. It's gross, but fascinating. I am just really glad I'm not the cricket right now!!
