Tovina has decided that she sometimes does notice the cats and wants to pet them. This usually involves sneaking up on them when they are sleeping on the chair and then slamming both hands onto their head and body. The cats generally looked shocked and then move about 3 inches farther into the chair so as to get out of Tovina's reach.
Baba has been trying to teach Tovina how to gently pet the kitties. This is meeting with some success as you can see in the video.
Its a little hard to tell, but Roxanne is rolling over at the end of the video clip so that Tovina can pet her belly. Apparently that took all the fun out of torturing the cat because that was when Tovina decided it was time to move on.
