Our beloved baby boy keeps trying to bring in mice he’s captured in the catio. He is not killing them, just playing and maiming with them until we can get out to remove the mice. We’ve had one in the house and two that we’ve managed to prevent by locking the cat flap when spotted.
Does anyone have any advice on how we can prevent mice from entering such a deadly zone?! We’d have thought the stink of a big boy cat would keep them away.
