Stupid Simple DIY-Treat Tubes for Cats and Small Animals

I picked this trick up when I was a zoo intern. We would save toilet paper and paper towel tubes to use as enrichment for the smaller, usually domesticated, animals (rabbit, chinchilla, opossum, etc.), and I've adapted it for use with my cats. I also use these to hold everything from scrap embroidery floss to cotton swabs. It's so stupidly simple you can probably follow along just by the pictures, or with brief directions, but we all learn differently, so I'm going visual and verbal (well, textual?... that sounds a little, um...). Also, my nail polish is fantastic, and I wanted to show it off.

Start with an empty toilet paper roll, or cut down a paper towel, wrapping paper, aluminum foil, etc. roll.
