Santa Hat Pet Portrait

Use the attached photo of your pet. Keep the animal's face, markings, fur colour and body exactly as in the photo and change only the accessories and the background. Add a small red festive hat sitting naturally between the ears and a knitted [colour] scarf, then place the pet on a rug in front of a decorated tree with warm lights out of focus behind. Camera at the animal's eye level, an 85mm look, shallow depth of field, soft window light from the left. Photorealistic, aspect ratio 1:1. No people, no text, no watermark.
