Mischievous Cat Colour-Changing Mug

When it’s cold it’s a black mug with two yellow eyes staring at you out of the dark. Pour in hot tea and the scene lights up: a grey cat sitting on a branch, pushing a mug off the edge, and on the other side his defence, “Cats don’t break things, they merely test the law of gravity”.

The design is heat-sensitive: it appears with a hot drink and goes back to the dark as it cools. Perfect for anyone who lives with a cat and has lost count of the mugs knocked off the table.

A gift you unwrap twice: first from the paper, then with the first coffee.
