I have two cats. Brothers from the same litter. Both very different.
They are both loving. And loving to each other. Never fight ever.
One is a lap cat when he feels like it. The other. Never.
The one who isn't a lap cat follows me to the toilet every time. Every time. I work from home. If I close the door he pushes it open. Sits next to the toilet. Doesn't do it with anyone else.
If it's relevant, we have a cat flap, his brother goes out but is mostly in the house with us but the toilet watcher has never once used it. Will go out if the door is open.
Why does he follow me? Any ideas?
