​Catnip Blankets are available in both Regular and Crinkle variety. Each blanket is made with a flannel top and a broadcloth on the reverse and measure , approximately 15" x 20", both styles have a Velcro opening at the top to allow you to add the catnip (included) for your pets enjoyment. They are both machine washable, but I would suggest putting the crinkle blanket into a laundry bag and hang to dry so as not to damage the crinkle inside.
