Aggression in Cats – Causes, Signs and Solutions

Our feline friends are usually sweet, playful and utterly adorable. But like many other animals, they employ their own language to express their feelings.

In some cases, this takes the form of behaviors that can be perplexing and sometimes upsetting – aggression is a prime example.

This often occurs completely out of the blue. One moment, everything is serene and the next, you’re nursing a scratch or bite.

In such cases, it’s really important to remember that our cats aren’t acting out of spite.

More often than not, aggressive behavior is caused by discomfort, stress or fear.

And in order to manage feline aggression, it’s crucial to understand it.

Understanding Feline Aggression

Feline aggression is a deeply ingrained instinct that stems from a cat’s ancestral past.

Before domestication, felines were solitary predators that needed to defend their territories and hunt for food to survive.

Although domestic cats have long been removed from the wild, their aggressive survival instinct behaviors are still part of their genetic makeup.

Aggression in cats can take many forms. Typically, aggressive cat behavior is displayed in the following ways:

  • Arched Back
  • Puffing up of Tail
  • Hissing, Growling, Spitting
  • Flattened Ears
  • Dilated Pupils
  • Intense Staring
  • Teeth Baring
  • Swatting or Biting
  • Thrashing Tail

Causes of Cats Aggression

Feline aggression has its own distinct triggers. These are the most common types of aggression in cats.

The vet will then conduct a detailed health check to identify the potential cause of the pain.

In some cases, a veterinary behaviorist or certified cat behavior consultant might provide additional strategies to manage aggression and reduce stress.

Home Modifications

Depending on the source of the pain, you might need to make some changes to your cat’s environment.

For example, if your cat has arthritis, providing soft bedding and ensuring resources (like food, water, and the litter box) are easily accessibl.

Preventing Aggression in Cats

So how does one stop feline aggression towards humans? Is it possible?

Preventing feline aggression is indeed possible albeit to a certain extent.

But keep in mind that cats will display aggression under certain circumstances as a normal part of their behavior.

Nonetheless, here are some strategies that can help to prevent aggression in cats.


Early socialization is key. Kittens should be gently exposed to a variety of people, animals, and environments in a positive manner.

This can help them become comfortable with different situations and reduce fear-based aggression later in life.

Proper Play

Encourage appropriate play behavior. Never use your hands or feet as toys, as this can encourage aggressive behavior.

Instead, use toys that mimic prey, such as toys on strings or wands.

Environmental Enrichment

Provide a stimulating environment with plenty of vertical space, hiding spots, and toys. This will reduce stress and boredom.

Avoidance of Triggers

If you’re awared that some situations will trigger aggression in your cat, try to avoid these as much as is possible.

For example, if your cat becomes aggressive when guests are over, provide a quiet, comfortable space for your cat to retreat to.

Regular Veterinary Care

Regular vet visits can help identify and treat health issues that could cause pain-induced aggression. You may also get tips on how to manage your cat’s aggression.

Behavioral Training

As mentioned, reward-based training methods can be used to discourage aggression and encourage positive behaviors. But they’re not necessarily preventative.

While these strategies can help prevent many cases of aggression, it’s always important to seek professional help if your cat displays persistent or severe aggressive behavior.

A vet or a certified cat behavior consultant can provide more personalized strategies based on your cat’s specific needs.
