Someone is confused around here!

This morning Dr. Daddy and I were having a quiet breakfast (Eirena was sleeping in) when our attention was grabbed by Uc. Our female dog was on top of Efendim (male cat) and was *ahem* making thrusting gestures with her pelvic area. Now either I am very confused as to what she was doing, or she is confused as to both gender positions and species. I grew up with only male dogs so it is possible that she was doing some mysterious actvity that I was unaware female dogs did. But sure didn't look too mysterious. Thankfully Eirena was sleeping.
