Photo of this sheepy (most of the face censored with a 🐏 emoji) wearing pink and white cat ears. Its hair is a bit messy.
It is wearing a dark blue jacket and orange backpack straps as well as the green strap of a shoulder bag is visible.
In the background there's a blurry grass field with some hard to recognize animals grazing on it.
