If you’re a cat owner, you’ve likely witnessed the classic feline maneuver: your cat locks eyes with an object on a table, gently nudges it to the edge, then swats it off with unmistakable confidence. While it’s undeniably amusing (and sometimes infuriating), this behavior leaves many pet parents asking, “Why do cats knock things over?”
In this article, we’ll explore the science, instincts, and psychology behind this behavior, while offering practical tips to manage it. Understanding why cats do what they do is the first step toward building a stronger bond with your furry companion.

1. Why Do Cats Knock Things Over? The Role of Feline Instincts
Cats are unique in that their behaviors are deeply rooted in their natural instincts. Even the most pampered house cat retains the hunting and survival traits of its wild ancestors, and knocking objects over can be traced back to these primal roots.
Hunting Practice
Cats are natural predators, designed to stalk and catch prey. In the wild, they often tap, nudge, or paw at their targets to test for movement and viability. This behavior allows them to determine if their “prey” is alive or worth chasing. When your cat sees a small, movable object, like a pen or a phone, their instincts kick in, prompting them to engage with it in the same way.
Exploring Their Environment
Cats are incredibly curious creatures. They don’t just see objects—they explore them. Knocking things over helps them investigate their surroundings, giving them tactile and auditory feedback. This curiosity is especially pronounced in kittens and young cats, who are still learning about their world.

2. Attention-Seeking Behavior
Sometimes, cats knock objects over not out of instinct but because they know it works as a surefire way to grab your attention.
Negative Attention is Still Attention
Cats are highly observant and quickly learn what behaviors elicit a reaction from their owners. If your cat notices that knocking over a glass gets you to look at them or talk to them—even if it’s to scold them—they’ll repeat the action. To a cat, attention is attention, whether it’s positive or negative.
The Link Between Boredom and Mischief
Cats are intelligent animals that need mental and physical stimulation to stay happy. Without sufficient outlets for their energy, they may resort to creating their own fun. Swiping objects off tables can be a form of entertainment, especially in the absence of toys or engaging activities.

3. Stress, Anxiety, and Emotional Triggers
Cats are sensitive creatures that react strongly to changes in their environment or routine. If your cat is stressed or anxious, their behavior might shift in ways that include knocking things over.
Displacement Behavior
Displacement behaviors are actions cats take to cope with stress. Knocking objects over can serve as a stress reliever, much like how humans might fidget when nervous.
Changes in the Household
Introducing a new pet, moving to a new home, or even rearranging furniture can unsettle your cat. They may knock things over to regain a sense of control or to express their discomfort.
Signs of Emotional Distress
If your cat is displaying additional signs like hiding, over-grooming, or aggression, their destructive behavior could be a sign of deeper emotional distress. It’s essential to address these issues holistically, often with the help of a veterinarian or animal behaviorist.

4. Health Issues That May Contribute
Not all instances of knocking things over are behavioral. Sometimes, underlying health issues play a role.
Declining Vision or Balance
Older cats or those with medical conditions may have difficulty navigating their environment. A senior cat with declining vision might bump into objects and accidentally knock them over. Similarly, cats with vestibular issues (affecting balance) might misjudge their movements.
Excess Energy in Younger Cats
On the flip side, young cats, particularly kittens, have boundless energy. If their environment doesn’t offer enough stimulation, they’ll often channel that energy into mischief, including knocking objects around.
When to See a Veterinarian
If your cat’s behavior changes suddenly or if knocking things over becomes excessive, it’s worth consulting your vet. Unexplained changes in behavior could signal underlying health problems, such as hyperthyroidism, pain, or neurological conditions.
5. How to Prevent Cats from Knocking Things Over
While it’s impossible to stop a cat from being curious, there are practical steps you can take to reduce the likelihood of them knocking things over.
Provide Enrichment
Interactive toys, puzzle feeders, and climbing structures like cat trees can keep your feline friend entertained and mentally stimulated. When your cat has better outlets for their energy, they’re less likely to engage in destructive behavior.
Secure Breakables
Cat-proof your home by keeping fragile or valuable items out of reach. Opt for heavy decor or use museum putty to anchor items in place. This simple step can save you a lot of frustration.
Double-Sided Tape and Deterrents
Cats dislike sticky textures, making double-sided tape an effective deterrent for areas they shouldn’t climb. You can also use motion-activated deterrents or sprays with scents that cats find unpleasant.
6. Training Your Cat to Avoid Destructive Behavior
Training a cat might seem daunting, but with patience and consistency, it’s possible to modify their behavior.
Redirect Their Attention
When you catch your cat eyeing an object they’re about to knock over, redirect their attention with a toy or treat. Over time, they’ll learn that there are more rewarding ways to play.
Use Positive Reinforcement
Reward your cat with praise, treats, or affection when they engage in appropriate behavior. This encourages them to repeat those actions instead of knocking objects over.
Avoid Punishment
Scolding or physically disciplining your cat can backfire, leading to fear or increased misbehavior. Instead, focus on preventing the behavior and rewarding positive actions.
7. Scientific Insights into Feline Behavior
Understanding the science behind cat behavior can provide valuable insights.
Cause and Effect Mastery
A 2016 study in Animal Cognition found that cats understand cause and effect relationships, as well as basic physics. This ability allows them to predict how objects will behave when they interact with them, which likely adds to the appeal of knocking things over.
Whisker Sensitivity
Cats’ whiskers are highly sensitive, helping them gauge the size, shape, and movement of objects. This sensory feedback may contribute to their fascination with objects on tables and shelves.
8. Fun Facts About Cats and Their Quirks
Cats are endlessly fascinating creatures. Here are a few fun facts to deepen your appreciation for their unique behaviors:
- They’re Crepuscular: Cats are most active during dawn and dusk, which might explain why they’re prone to mischief during early mornings or evenings.
- Highly Adaptable Hunters: Even indoor cats exhibit behaviors like stalking and pouncing, mimicking their wild counterparts.
- Communication Masters: Cats often use their behavior to “talk” to us, whether it’s through knocking objects over or meowing for attention.
