This is my first boa althoguh I've had other snakes, colubrids and a ball python. S/He's about 21" at the moment and I thought looked absolutely awesome with the way it's saddles are.
It did try and bite me twice yesterday when I was fixing some stuff in its tank and had to take it out for a sec.. I was holding it and it struck at one hand and then it struck at my thumb on the hand I was holding it with. I don't see how it missed, but oh well. I'll let it settle one more day before I start taming it down.
Also, I'm not completely sure what size rat/mouse to feed it. I'm thinking something thats about 2 inches, maybe a hopper or a rat fuzzy. I know the 1.5 rule and all, just curious as to what you guys use for your snakes when they're >2ft
