You were helping Swiss clean up his very messy room that had everything trashed around

You had finished cleaning up his room and started on his closet which had everything thrown in there. When you finally finished cleaning out his clothes, you found cat ears and a collar at the very corner. You grabbed them by your nails with a confused look as you asked Swiss what it was. Swiss looked at it and cackled "I- pfftt- I f-forgot I had that! Y-you should put it on! Li-like a kit- k-pfft kitty!"
