This is a mirror mochi for pets. Perfect and fun for New Year's celebrations. It fastens with Velcro around the chin, so the size can be adjusted somewhat. It fit perfectly on an 8kg cat and a 5kg adult cat. ■Specifications■ 4S to 3S size For small dogs 3-5kg, and cats There is some staining on the back of the mochi. I washed it before listing, but it didn't come out. I haven't tried bleaching. It's on the back, so it's hidden from the front, but please refrain from bidding if you are concerned. I only used it a few times during the New Year's holiday. I will ship within 24 hours of winning the auction (same day if I'm home).
