Misty has started doing this recently, she doesn't latch on though, just sits gyrating next to me. :roll: I think it is probably excitement, as Gilly says, with a bit of attention seeking thrown in.
Jimmy gets amorous with towels too, it can be a quite a struggle disentangling him after he's been dried. You have to be quick.
About a year ago he sneaked off to my bedroom and fully consumated his relationship with my duvet. :shock: He hasn't done it since fortunately, so maybe it was just a one night stand.
