For the past few days, my male cat Sterling has been trying to mate with my female cat Daisy. On the ironing board, in my office/sewing room.
Both are neutered, of course, and Sterling really hasn't any idea what to do after he sinks his teeth into her neck scruff, so he just kind of stands there over her looking confused - but determined to do *something* - until she gets fed up, turns around and whacks him.
She puts up with this because, otherwise, they are best buddies.
This is all the more amusing because it takes place on the ironing board, which is not particularly sturdy. I had to move the iron because they kept knocking it off.
Now that their nightly drama has been accomplished, they're engaged in mutual grooming of each other's heads, which is really cute. It's like Daisy is thinking, "I have no idea what you're trying to do, but I love you anyway."
Come to think of it, I've often thought the same thing.
