Some things are not up for discussion.

This mug makes it very clear where the boundaries are. Featuring a grumpy cat guarding its coffee with full intent, it’s for mornings when sharing is off the table and patience hasn’t arrived yet. Perfect for desks, kitchens, and anywhere someone might think about touching your drink. The message is simple, the vibe is firm, and the coffee is yours.

Fill it up. Hold it close. Make eye contact if necessary.
