I have just witnessed a totally daft scene! My cat Silvie and Charlie cat who lives next door are the stars.
Charlie was on the shed roof and Silvie on the ground below, both rolling around and eyeing each other. They have this kind of love hate relationship, always have. Then Silvie decides to wander off so Charlie chases her. They come to a stand off in the passage between our houses. They hiss and spit and growl at each other, and then both stalk off in opposite directions, ears still flat, backs still arched and tails still bushed!
Thay are so funny - they do that kind of fighting where there is a horrendous noise from both of them, an enormous amount of frantic paw-waving, but hardly any physical contact is actually made. I think they have an understanding - Silvie has the size advantage and Charlie has the brains (she's very little but incredibly feisty!) - they seem to know that there's no point in proper fighting so they have to go through this pretend fighting ritual every now and then.
I have to wonder if it isn't all for show and that they're best friends when they know us hoomans aren't looking!
