Two cats are curled up together on a gray, textured surface, possibly a cushion or garment. A gray-and-white tabby cat is curled tightly into a ball on the left side of the image. To the right of it, another cat with brown, white, and black markings is awake and looking towards the camera with green eyes. A blue-and-white cardboard box is partially visible in the top-left corner of the image. Part of a gray and black shaggy blanket is in the top right corner of the image. The image was most likely taken indoors, but there are no distinguishing indicators about the location that would place it in the city of Shumen, Bulgaria.
