Frantic fun, Scalextric for cats!
My little Peggy didn't take long to get the hang of this, and happily clatters away with it all night (luckily I'm a heavy sleeper). My other two are elderly and seem content to watch her play, or squeeze into the box it came in.
After adding the extension pieces the scope for layout variation is enormous, even though there only seem to be three different types of track piece (and only two in this starter set). For large layouts, having more than one ball in the track at once adds to the fun.
