Characters in the series (with the expection of human characters, Eggman etc.) have been in the most part complied with the cartoon logic with female characters only having clothing (minus gloves and shoes), but then again that's what characters like Felix the Cat have been doing from the beginning. It's no wonder, that seeing even male characters having clothing does seem bizarre for many years later, if it becomes recurring characteristic element in certain part of the franchise, as a prominent  example now being this.
