@Catsos I'm afraid after reading all what you have done, some on MN might find it quite and funny.
But to be completely honest even as a cat owner, If it was my home you have done this too. The first thing I would be doing tomorrow is taking photos and going straight to the police and my solicitor.
You sound horrendous, trespass, damage and putting stuff in the house and not controlling your pet, I would be livid.
All the people thinking its funny i doubt honestly they would if was their new home.
As for the crab sticks and ham, I have no words!
