Abstract
A cat toy comprised of at least a partially transparent and generally spherical hollow external ball within which a second smaller opaque ball is suspended so as to form a uniform continuous gap between the two balls. The external ball is provided with an opening through which small balls having diameters only slightly smaller than the height of the gap may be inserted or removed from the gap. The opening is normally covered by a removable section. The external ball is also provided with at least one access opening having a diameter smaller than the diameter of the small balls but large enough to allow a cat to insert a single cat paw there through in order to bat at the small balls.
