The Mustard Cat Coffee Crew reusable coffee cup has a very cool design & is made to keep your drinks hot. For anyone with a bit of style or any cat lover, this reusable cup is a must have & will make drinking hot beverages a much more fun & enjoyable time. The cup is ceramic & has a silicon lid (with cat ears of course!) & the double wall ensure the contents say hot inside but the exterior is just warm & fine to hold. Please take good care of the cat by not putting it in the dishwasher or microwave.
