This may sound strange.... I had my BP Ari aroud my neck last night and the night before while watching TV and knitting - yes I knit. I am using a new super soft yarn and both evenings she has strectched out and wrapped herself around my knitting needles as if she cant get enough of the material. She has not done this with my other cotton yarns before - it seems to be this material specific. Any thoughts on whether snakes have a preference in material or textures they can feel?
