Hi, my 3 yr old male rescue cat will sometimes lunge at me and clamp himself onto my legs. He only ever does this when I'm alone with him and has never done it to DH, who thinks "he's only playing". Well he hasn't seen him do it and it certainly doesn't look like he's playing to me! Other times he'll sit happily on my lap and be as nice as pie, again something he doesn't do with DH. When we took him to the vet recently for his yearly check up it mentioned it as advised in books and forums, but she couldn't have been less interested, only saying that some cats have complex behavioural issues and offering no advice. He's our first cat and don't really know what to do about it - any ideas anyone?
