Why Do Cats Knock Things Over? Is This Normal?

A: Yes, it’s completely normal for cats to knock things over. It’s part of their playful and mischievous nature. Cats can knock things over for several reasons, ranging from instincts and curiosity to attention-seeking and boredom. 

We talked with Mieshelle Nagelschneider, cat behaviorist and owner of The Cat Behavior Clinic in Seattle; and Stephen Quandt, CFTBS, founder of Stephen Quandt Feline Behavior Associates, LLC, in New York City to learn more about this quirky and chaotic behavior. 

Generally, cats knock things over because they want something—whether it be to entertain themselves, get your attention, or find out what those clear doohickeys are that you drink your water out of. 

Here are the most common reasons cats knock things over, according to our experts. 

Curiosity is in cats’ DNA. In addition to their exploratory nature, they’re also incredibly observant. So, when they see us going about our day and picking up certain objects, this can contribute to why they focus on things, like water glasses left on the counter, Nagelschneider says. 

Consider giving your cat something more appropriate and interesting to stick their paws in or to try to knock over, like the Catit Senses Cat Digger Slow Feeder or the TRIXIE Activity Fun Board. This also encourages them to work for their food. 

Interestingly, knocking things over is instinctive for them and can be connected to predation.  

“Motion triggers a cat’s predatory instincts, so setting something in motion can appeal to their predatory nature,” Quandt says. 

If your feline friend has an affinity for knocking items off counters, it’s because of the excitement of the movement of prey—much like they would bat a stuffed mouse across the floor, Nagelschneider says. In this case, the glass of water you set on the counter is the prey. 

“Think of a toddler who likes to drop items from their high chair,” Nagelschneider says. “It’s all about the excitement.” 

While our kitties can seem unapologetically independent and aloof at times, they do love us and yearn for our attention. (On their terms, of course.)  

One of the ways they ask for—er, command—that attention is by engaging in certain behaviors, such as knocking objects off surfaces, rubbing against your leg, and staring at you.  

Our experts say that cats may learn that the behavior of knocking things over elicits a response from us. As a result, they act out to gain our attention. 

A simple solution to this is spending more time bonding with your cat and showering them with as much affection as they’ll allow. 

Cats are bright, inquisitive, and athletic. If they find their environment too mundane or they don’t have enough enrichment, this could result in boredom, prompting them to find ways to keep themselves entertained. 

“Cats are easily bored, and so knocking things over becomes a type of play-based behavior,” Quandt says.  

Providing your cat with different play options, such as the Frisco cat toy variety pack and puzzle toys, like the Nina Ottosson by Outward Hound Buggin’ Out, can help keep them mentally stimulated. 

Another reason cats could knock things over is out of hunger, Nagelschneider says.  

If you notice that your cat always seems to be hungry despite being fed appropriate portion sizes, it’s best to consult your vet to find out what the underlying cause may be. 

Daily exercise is essential for a healthy, happy kitty. A cat who has excess energy might resort to zoomies, tipping over random objects, and getting into mischief as a way to put that energy to use. 

Fortunately, there are plenty of activities and games you can play with your cat to help them stay physically and mentally active—without the unexpected destruction. 

Knocking things off surfaces is normal cat behavior, but in some instances, it could be considered highly undesirable, especially if repeated often, Quandt says. 

The good news is you can manage or redirect the behavior—and keep your belongings in place and intact. 

Here are tips to help stop your cat from knocking things over: 

Scheduling playtime with food rewards can be a great way to bond with your cat and stop them from knocking things over.  

Quandt recommends relieving your BFF’s boredom with a range of toys, such as interactive cat toys, puzzle feeders, teaser wands, toys with catnip, and motion-sensitive toys.  

Some fun options to try are the Frisco butterfly cat tracks toy, Catstages Kitty Cube puzzle toy, SmartyKat Instincts electronic motion cat toy, and Frisco Fabric Teaser Wand Cat Toy.  

You can also make your own cat toys using household items! 

When you discover your usually orderly office supplies and knick-knacks knocked over, this can pose the question: Why do cats knock stuff off shelves? Many cats naturally love vertical spaces, meaning anything on shelves may end up on the floor.  

You can give them their own space to safely explore and laze by installing cat shelves, like the Frisco cat bridge wall or Armarkat real wood cat wall additions, or providing tall cat trees such as the Frisco faux fur cat tree or the Coziwow floor-to-ceiling cat tree tower. 

A good way to engage your cat’s innate instinct to hunt is with interactive play.  

Nagelschneider recommends a seeking circuit toy, like the Catit Senses Super Roller Circuit toy, where the prey hides so your cat can hear it but not see it. This is the best way to satisfy your cat’s need to see prey run and hide, because it’s that part of the hunt that triggers the biggest feel-good brain chemical release, she explains. 

You can also try the Doc and Phoebe’s Cat Co. Indoor Cat Hunting Feed Kit, which provides a great way to satisfy your cat’s need to hunt for prey. 

Nagelschneider recommends reading the feeding guidelines on your cat’s food label to ensure they’re consuming enough calories for their weight. You can also increase the frequency of their daily meals.  

Consult your vet for personalized recommendations on how much to feed your cat. 

Ultimately, the key to keeping your feline friend from knocking over your belongings is giving them something better to do, Quandt says.
