If your kitty goes through catnip toys fast, make your own! Spritz a balled up, clean coffee filter with catnip spray. Your kitty will play with this because the woven fibers will hold on to the scent so this inexpensive kitchen staple will give her hours of fun. When it flattens or gets soggy, replace. The best way to keep on top of this is to make several at a time, place in a Ziploc plastic bag, so they will be ready when she is.
