Two cats, like to come and go as they please. Had them 10 years and use an open car flap which was already there when we moved in and is massive. I've tried replacing it but can't find one big enough.
Few months ago a cat started coming in and eating my cats food. He's now venturing around the house (runs when he sees us). Mine are nervous but useless. They just watch him eat their tea.
Is there anything I can do?
Def can't afford a microchip cat flap (or a new door to fit it) and mine won't wear collars (so can't get one of this to activate a cat flap)
Am at a loss. Really don't want to have a third cat.
