Every professional sports league has rules that teams must follow. Failure to do so usually results in a fine to help discourage teams from continually breaking the rules. However, most teams never expect to get fined over a cat.
During a game between Besiktas and Bayern Munich, a cat ran on to the field and delayed the game until groundskeepers could shoo the cat off the field. Because of this delay of game, Besiktas was fined all because of a cat.
