Yeah cats are wild and always do their own thing. I feel bad if my cat wants to go outside and I won't let him to. He is just gonna punish me with excessive meowing lol. But yeah there are stray dogs outside, and stray cats too... Most stray cats can fight, hide and escape from the dogs. I love stray cats, they are strong lol. I don't want my cat to be a stray cat but I want him to be able to fight and escape when needed.
