Not sure about the Purr-pad. We have those little cotton throws everywhere around the house. They are too small to be a blanket, unless you are a child. It might be big on a sofa arm, but they are easily folded down to a smaller size, and easily washed. Cheap too. Our guys love them. They do double duty as tunnel ceilings also. We line the sofa cushions up in a row and then drape the cotton throw over the cushions and the back of the sofa. Can't beat a tunnel as a play area.
