Made me smile this post , Ferals can do so much damage , mid 1980s i was asked to sort out ferals in a football stadium/stands . The damage they had caused was catastrophic to the club , Seats were covered in muck on match days and had to be cleaned and disinfected twice a week , Concrete was literally rotting away as were the steel girders holding up the roof , Pretty sure on one outing my shot count exceeded 152 , I used to bag them and the local authorities came to pick them up for safe disposal . They certainly need to be kept in check
