Stupid cat!

We were watching Springwatch the other evening and there was a passage of just birds singing and Mittens became agitated.
She has suddenly become very interested in TV
The photo shows her watching some fish and if you watch the short video link https://youtu.be/3-RxHseqgaU you can see more.
She looked behind the TV, looked over it etc
P.S. I’m really enjoying this series of Springwatch.
