Does anybody else have a cat as weird as mine?

I know you are probably thinking why is she asking a dumb question like this at 3 something in the morning? Lol but i am up and watching my cat and it just dawned on me that he is unlike any cat I've ever came into contact with. For starters he was born outback of my house but I could never catch any of the kittens. Than as he got older he would literally come into our yard while our two dogs we're out there. He was still afraid of people at that point but wouldn't think twice about fighting our dogs pitbull & yorkipoo. Since than he has become a house cat only and he Is totally lovable but he has some extremely weird ways. When someone knocks on our door he normally beats the dogs to the door and meows as the dogs bark. Also he comes when he is called no matter what he is doing he will stop and come running. If we hide under a cover and call him he will meow and dig at the blanket until he finds an opening. When he fights out yorkipoo he puts him in a head lock and flipS him onto his back. And it's nothing to him since he is almost 17 pounds. Oh and whenever i have my kids in the tub and the door is shut he crys bangs his body into the door and scratches at it until I open it. Than he lays in entrance of the bathroom and watches them in the tub until I take them out. These are just a few weird things he does. Sometimes I wonder if he knows he's a cat? But does anybody else have a cat that is not normal? Lol.
