@dlowan,
Latest appalling behaviour.
Both cats have taken to dive-bombing my head...fortunately mostly when it is under the covers.....when they know I am awake but I am not getting up to get their breakfast. Once upon a time, only Viola did it. They take it in turns now. They sit on my knees, wiggle their bottoms, then spring into the air, landing on my head, wrapping their legs around it firmly and biting.
The other morning, Viola was sitting on my chest with her bum in m face, to show her love for me. She was blocking my ipad, so I asked her to move. She wouldn't, so I gave her tail, which was pretty much in my mouth, a gentle nip.
She rounded on me and biffed me so hard that my glasses flew across the room. She was so pleased to see that that she gave me a kiss.
It's a battle, and I am not winning.
