Is there a specific reason for Saturday?
The person offering it is kind enough to make you not need to fursuit on weekdays when you're more likely to work. But people like to do things on Saturdays. You must do everything on Saturdays in a fursuit. Family reunion? You're in a fursuit. Hanging out with friends? I hope they're furries, because you're in a fursuit. You get the idea.
You must wear it starting at midnight.
