My nose be, Poseidon, will climb the cord for the curtains to get from the plants in my window to his favorite perch (a bend-a-vine that hangs from a curtain rod bracket). He gets a little freaked out when it starts swinging around as he's climbing it but he still does it every time I let him roam around. I guess it just depends how bad they want to get to the other end of the rope lol.
