Cave Canem Doormat — Pompeii's Original "Beware of Dog" Mosaic for Your Entryway

Around 2,000 years ago, somebody in Pompeii commissioned a mosaic of a snarling black dog with the words CAVE CANEM — beware of dog — and history's first passive-aggressive doormat was born. The dog is long gone. The joke still works. Now the most famous floor in the Roman Empire can guard YOUR threshold, whether your actual security system is a 9-pound terrier or nothing but vibes.

Choose all-natural eco coir for covered entries out of sun & rain — 8 sizes, from a tiny 12" x 26" to a Colossal 36" x 72" worthy of a villa — or all-weather recycled rubber that lives anywhere and hoses off after every toga party. It's the gift for the Latin teacher, the art history major, the classicist, & anyone who came home from Pompeii wanting the one souvenir the gift shop couldn't sell them.

We're Damn Good Doormats, the original custom & sarcastic doormat company since 2009 — but the Romans beat us to this one, and we know when to bow. Questions on size or spot? Perogi, our chatbot assistant (a very good pug and no relation to the mosaic), can help, or read How Do I Choose a Doormat?

Cave Canem! — As a contemporary replica, the doormat is in no way inferior to the ancient model: creative, high-quality manufactured and you don't even need to be a dog owner. 😉 I am very satisfied!

Shipped very quickly, packaged well and exactly as pictured! Seriously excellent quality for a doormat-- we've been in the market for a new one for some time but everything seemed flimsy or like the text would wear out right away. This doormat is perfect and exactly what we wanted! Thank you so much!!!

This exactly what my house needed. Damn Good Doormats had been on my radar for a while, but I just couldn't settle on something until this Cave Canem doormat struck me right in the Latin/Roman heart. And, of course, Miss Daisy approves.
