Nope, you don't spoil your cats either. None of us do.
I don't allow my cats to get on things ever.
I don't allow them to sit on my quilting, but for some reason I use masses of rollers to get off the long white hairs just like my white Persian.
I don't allow them to sit near my computer because of cat hairs.
I've discovered that a curved eyelash curler can get masses of long hairs from the computer keyboard and sewing machine bobbin area.
