Good morning!
I was browsing the pets section of craigslist today (which I really ought to stop doing...

) and I saw this boa. I contacted the seller and this is the information I have. Not having any experience yet with boa constrictors, I wanted to see what you all think. His enclosure certainly caught my attention...
The seller claims that the snake came from a friend of a friend who couldn't care for him. He eats a live mouse about twice a month. He says that he is able to handle him, but is still bitten on occasion. He wasn't able to tell me the size of the tank, but I would guess it's a 20 gallon. He guessed that the boa is about 2-2.5 feet long. He says the friend of a friend told him the boa is about three years old...
He acknowledges that he can't take care of him properly and has actually waived the $100+ he was asking on craigslist AND has offered to deliver the snake to me.
Here he is.
