Hubby decided it would be a good idea to bring the outside cat in, so he bought it into the living room. But it was not happy and struggled out of his grip. Our boy cat followed him as he’s friendly, but the outside cat turned round and hissed and swiped at him. I showed him where the cat flap was. He scarpered. Then as our female cat came to look at what was happening by the backdoor the abandoned cat lashed out again, this time from outside the cat flap. Result three confused and upset cats! So next time we will try a more gentle integration.
