In 50 years of owning or being owned by cats none of them have ever properly watched TV. Oh Yes they have stared at it in a disinterested way. If they happen to be facing in that direction, but nothing stirred them.
That changed with my female cat which I have had for a couple of years. She started by watching little things like birds and mice, but she really did get interested when we watched cat programmes. Now she seems really into things like lions. I got a few photos a couple of months ago of her standing up and looking at the screen. How does she know, or not, that there is a genetic linkage with big cats? Do they move in a similar way? Was it the noises they were making….. I don’t know. I think it’s cute behaviour and I also think she’s a lot cleverer than her brother.. . You should see her play.
