That's all I've been saying to him for the past few weeks! I don't know what his problem is, but he keeps trying to hump my male cat! It's getting very annoying. He never does it to my female cat, only my male cat, Gizmo. I've tried yelling at him, spraying him with a water bottle (which he thinks is a game) and I just don't know what to do. I think maybe it's time for him to get neutered. I just really don't want to do that...what can I do?
