The main purpose of the visit was to see Henry, who's going to come live with us once we get back from our holidays. Fortunately, Amy wasn't too allergic (she got a bit snotty, but her eyes seemed ok). Henry seems like a dude, he didn't seem to mind Amy fussing him, or me not fussing him. In fact, the only thing he seemed to be concerned at all about was his dinner (but then that's cats I suppose).
Amy and I are already looking forward to him coming to live with us. It'll be great to have the patter of paws around the house.
