That's the truth. We have two cats as well, and the only thing I can get them to do when I want - is eat. they both have the habit of getting onto the roof, and there is no way they will come down, until they are ready to do so.
I have four cats and I've teach them to walk with me when outside, they know when I say "lets go out" that it means going for a walk. They also know what treats, eat and playtime and combing (they liked to be combed)is. Yes, they stay with me when going for walks.
That’s because cats have all the dignity that dogs unfortunately lack.
