Damage caused by humans or animals

One of the main disadvantage if there is no one at home, is that the risk of trespassing is very high and the person trespassing may or many not take valuable items. After the home owner has come back , it is very difficult to find out whether the damage is caused by animals like rats, mice, cats , squirrels, birds or other or by one or more human being
When there is a hole or damage to the doors a person can be assured that human trespassers were involved, however when small items like flowers are stolen, pet food disappears, it is difficult to find out who is responsible.
In many cases, all the items on the shelf are disturbed, some of them are on the floor, and there is no sign of tampering
