I have two cats- a brother/sister pair that are 13 years old. I've been ordering cat nip filled mice from The Creative Mind on Etsy for the last few years for their Christmas presents. These are awesome by the way! Very durable and way better catnip than the toys that you can buy at the big box stores. But, I saw this pattern from Simplicity last year, 8284 , that got me thinking that I could sew a little homemade something for them this year.
