Here is the cat!
A acquaintance told me. They have a cat, and they are very clean. And they and his husband taught him to go to the toilet, but not just to walk, but also to wash behind! Her husband adjusted the mowing mechanism for a long time so that the button would move softly.
And here one day the owner noticed that the cat, who went "in his business", something for a long time does not get out. When she looked at the castle, she was in shock. During this time, the cat pressed the slide, listened and pressed again.
It turns out that day the cold water was turned off for two hours!
