Honey the Betta Watches the New Sofa Drama

We finally bought the new sofa, and the first thing that happened is that our neighbour's cat moved in. Well, not in, but onto our balcony railing, staring at the living room as if she had paid for the furniture.

Honey, my six-year-old betta, is not amused. He flares his fins every time the cat appears behind the glass. I think the sofa is fine. The cat is the problem, and so is my decision to put the tank right next to the window.
