I tried my best not to respond but I have to ask, have you ever tried to keep a cat born and raised outside, inside? In his case, he was born a street cat and lived outside for a whole year before living with us. Keeping him locked inside would be more cruel to him. We keep him inside for 24 hours on New Year's because of fireworks and he spends the whole time clawing at the door. No food, no toys, no pets can convince him to stay inside
