Just a Guy Who Loves Cats mug,  funny cat mug, gift for him. Back reads: Real men Love Cats Great Men Change the Litter Box. Inside is glossy black. My tribute to dudes everywhere who help out with the four footed babies. Some men are born to cats- others have cats thrust upon them. Either way, this mug will make them smile. Handmade Stoneware mug fired to over 2000 degrees and created using all non toxic. lead free materials. The mug measures 4 x 4  and holds 16 oz. Safe to place in the dishwasher and microwave. Made to be used and enjoyed!
