I can't figure out our cats. We've had the female since she was a kitten. The male cat we got when he was four years old. Both cats are fixed.
Sometimes they get into big fights. They bat each other with their paws or maybe bite each other. The female growls, hisses, and yowls. She rolls over on her side and looks like, "you can come and get me at any time." Yet, she can get away at any time. The male cat doesn't utter a peep.
I also give them treats in their dishes. Sometimes the female cat walks away and leaves something for her brother.
Then sometimes we see the female cat grooming the male cat or both of them cuddling together. Either they have short memories or their fighting is just playing -- which we have decided it really is.
