My cat is around 2 years old, and he's more of an outside cat. Lately, it's been snowing so he can't go out a lot, and he's been showing some weird behavior ever since. I don't know if it's because he can't go outside or what, but when we call him over to cuddle by patting our stomachs or just calling him over, he'll come over and his eyes/pupils(?) will get big and he'll start purring and meowing really weird and get up in our faces, and then he'll start to bite us and kick his back legs when he does so. We tell him no and gently push him away but he'll just grab hold on another object, like my mom's robe or a blanket or whatever he can get his mouth on and kick his hind legs. What does it mean? People tell me it's my cat telling us he owns us, but I'm not too sure.
