Animals around the world are being abused and killed almost every single day. Certain people abuse their pets that they had but do not care about. The animals being abused either become scared of humans or aggresive and defend themselves from them. An example of some animal abuse is dog fighting. Dog fighting is when they force two dogs to fight for entertainment.
Almost 70% of dogs are suffering from the abuse in dog fights and some are just left without food and water. About 20% of the abuse goes toward cats. They are thrown into the streets to fend for themselves. That is why America has so many strays or "Ferrel" cats.
