I saw a lady online a while ago that had knitted a sweater for her boa constrictor. It was basically a long woolen tube about 5 feet long that fit the snake snug with just the snake's head and tail hanging out. It was quite funny, but the snake seemed to not mind it. She was holding him while he wore it. I have been trying to find it again so I could post it but i can't find it now. (I should have bookmarked the page).
Anyway, if any of you ladies know how to knit.................... (hint hint)
