Vintage Cat Mug with Tail on Handle Black and Gray Tabby Coffee Tea Mug

Vintage white coffee mug with a black and grey tabby cat on one side. The cat's tail extends onto the handle. The handle is flat. The mug is one-sided printing. It is possibly vintage 1980's Japan mug. It is used, but in good condition. There is some very slight wear or scuffs toward the bottom of the mug and on the bottom. There is a manufacturing flaw in the glaze toward the top of the mug. See photos. It measures approximately 3 3/4" tall x 4 3/4" wide, including handle.
