Ok, so theres a utterly adorable grey tabby tom outside my back door, everynight for the past 3 days now trying to get at my Dayzie. Tonight, not a mear 20 seconds a go, he chased her around the garden, sniffing everywhere she has sat, walking around mumbling and trying to get in the house. at first I thought it was cute but now it's rather annoying. How do I stop him from coming to my garden and leave my Dayz alone (who has been spayed) he's like an obsessed stalker!
