TRY TO THINK OF A GOOD CHEMISTRY PUN. ALL THE GOOD ONES ARGON.

Claiming that cats nap periodically is pretty generous of us. Cats nap whenever possible. Although, we have to admit: we also nap whenever possible. Unfortunately, our opportunities are much more limited since we have to bring the bacon home.

But when you do get the chance to catch 40 winks, do it in feline style with this Periodic CAtNaP Pajama Shirt and Short Set. The cropped tee comes with a pair of shorts highlighting different elements, perfect for the lover of Chemistry Cat memes in your life.
