I take dumps with the door open because it's just me and my wife and we have two bathrooms anyway. Plus, it encourages my wife to leave my side of the house alone.
Anyway, as soon as I sit down on the crapper my cat runs in meowing up a storm. Then she'll hop up on her own crapper which is parked a foot in front of mine and start purring really loud and headbutting me. Other times she'll hop up on the sink counter and head butt me from there.
Some times she'll see a prime opportunity to drop a load of her own, and we will both be on our respective crappers a foot away straining, our twin a$$ stenches producing a faintly harmonizing olfactory chord.
Then when I'm in the tub she'll hop up on the toilet next to me on sentry duty. Other times she will risk a leap to the edge of the tub and watch me from there.
As I'm writing this she just hopped up onto the sink.
