Hi My cat Gizmo will be two in July. My partner and I have recently split up and since then his behaviour has changed. He is constantly looking for food. He has recently been wormed so that is not the problem. I have another cat and he pushes her out the way. He has stared raking the bin if he gets the chance. He wakes me up at 5 am to be fed so I have started putting him outside if he does that but he screams constantly at the door. I do not know what to do. Has anyone else experienced this kind of thing?
