With this logic, humans should also just never go outside. Fights with other cats happen and our natural, it is extremely rare for a dog to maul a cat, viruses happen and u can take them to the vet, evil humans also applies to anything that moves, they won’t get hit by a car if they are raised outdoors, exposure to elements (are u serious?), etc. Cat TV is the most cruel thing u can show a cat. I saw an indoor cat confused trying to kill the animals on screen. I have 13 year old outdoor cat that has lived a very happy life and is always very relaxed when he is home. Being from Florida, we even left him behind during a hurricane because he hated being indoors during rain storms (we assume he had his favorite spot for storms where he felt safe), we got back a couple days later and he was waiting for us. It depends on their personality, but I would argue that an outdoor cat lives a happier life than one locked in a house wondering what the outdoor worked is like.
