Cat aggression is a common behavior problem and can be quite severe. Cats have five potential weapons that they can use against you when they become angry—their teeth and four clawed paws. Aggressive cats can be risky to have in your home as they pose a real danger to family and visitors. Cat bites can be painful, become inflamed, and may lead to an infectious disease called Cat Scratch Fever.
Aggression in cats falls into several categories. If you have a cat with an otherwise sweet disposition, you might see spouts of aggression when you visit your vet, vacuum the house, or when the cat experiences other loud noises. Such outbursts are examples of fear aggression and usually subside once the cause of the cat’s anxiety is addressed. A more lingering type of aggression is related to petting, brushing, and general handling by humans. We might see such outbursts in rehomed cats that have suffered trauma, been mishandled, or had other reasons to mistrust humans in the past. These cats can develop tactile issues later in life and have a very low tolerance for petting and brushing. Cats will also show aggression to guard their territories, defend their offspring, and protect themselves if they feel attacked. Such types of aggression might appear if you introduce your cat to a new partner, a new baby, or other pets, or if you redecorate your house.
