Animal cruelty is when someone deliberately hurts or does not properly care for an animal under their control. It can range from physical violence to deliberate mental distress or neglect.
If any law is being broken then contact the police immediately, but the police typically state that “if you see, or suspect, that a person may be treating an animal badly, whether this is physical violence, neglect or any other form of cruelty”, you should contact the RSPCA as they work with the RSPCA to investigate cases of animal cruelty.
