Do you know why your cat likes to knock things over? What’s your theory? In fact, does he do it? Not all domestic cats do. What percentage of cats do this? Despite what experts say I don’t believe we have a full and certain answer to these questions so I’ll provide mine but I’m not completely certain either. But this form of feline behavior strongly indicates the reasons given below.

RELATED: How do I know if my cat is bored?
Reason 1 – attention seeking
I have the distinct impression that when cats knock things over (say, off a table or shelf) they are doing it to arouse your attention. They are provoking you into action. They’ll do other things too, with the same objective (I discuss this below). The reason why they want to get your attention is because, as far as they are concerned, at that particular time, you’re not giving them enough attention and often the desire is to get you to provide some food or perhaps to go outside with them on a hunting trip. The fact that it is a time of day which is unsuitable to humans is irrelevant to the cat because we are cats to a domestic cat. They probably find it hard to understand why we don’t want what they want.
If this is true it tells us that cats are smarter than many people give them credit for. But sometimes the process of knocking things over or doing something which irritates the human is informally trained-in by the human. If the cat’s owner responds, as is likely, to something that irritates and which provokes a physical response, the cat recognises this and understands that their actions in knocking something over achieves the desired result and so they’ll do it again. Learning by observation.
Out of sync.- circadian rhythms
The domestic cat and the human are out-of-step in their biological clocks. When the cat has the urge to be his most active at dawn, dusk and during the night to hunt, the human wants to be his/her least active. At 4 am she is still asleep or barely awake. During late evening she is watching television or chilling out. Our cat sometimes want to interact with us at some of these times. Not all cats do. I sense that some cats give up on their hard-wired desires to be active at night and dawn because they are full-time indoor cats and they understand there is no point in fighting their natural instincts to hunt at night. This is not a rational decision; it is just that they unlearn these hard-wired traits.
Other ways to attract attention
My cat does not knock things over off shelves or tables. His habit is to lick the side of the bed. I think he did this initially because he likes the taste (it is cloth covered). He soon realised that it annoyed me and made me interact with him even in an unpleasant way (I’d push him out of the bedroom and close the door). Once he’d learned that licking the bed elicited my response, he did it at 4 am because he wants me to go outside with him on a hunting trip. Or he wants to be fed. He does not want me to roll over in bed and snooze. These days I feed him even if it is 4 am.
Reason 2 – boredom
There are probably other influences at play. For example: boredom. If a cat is bored he may prod items and push them off a table. But this is linked to the idea of provoking us to interact with them. If we did interact with our cat more he would not be bored. Perhaps this is a result of the well-known aspect of cat behavior: independence. It can lead us into ignoring our cats too much. Domestic cats are relatively independent but also sociable with other cats in the house. We are big cats.
Two more reasons which are extensions of the above
Here are some more theories/ suggestions on why your cat likes to knock things over taken from the internet at large but which are effectively extensions of the two reasons above.
Instinctive hunting but nothing to hunt: This is an extention of boredom above. Despite their cushy domestic lives, cats harbor ancient instincts. Their wild ancestors are skilled hunters, top quality predators, stalking prey through grasslands and forests. When your cat nudges that vase off the table, it’s like a miniature hunt. The mug or lamp becomes a substitute mouse or bird, and their delicate paw pads gather information about these “prey-like” objects. So, even though your ceramic cup doesn’t resemble a scurrying rodent, your cat’s primal instincts kick in. They are creating a prey animal, a living creature out of a dead, inanimate object on the mantlepiece.
Playtime galore: Cats adore playtime—it’s their version of a high-stakes adventure. Play mimics hunting, and your feline friend relishes chasing after string, feathers, or anything that wiggles. Knocking things over? Well, that’s just another thrilling game. Imagine your cat’s inner monologue: “Behold! The mighty pen holder! I shall vanquish it!”.
So, dear cat guardians, fret not! Your cat’s penchant for chaos is perfectly normal. To mitigate the flying objects, ensure they have ample enrichment (think cat trees, puzzle toys, and laser pointers), cat-proof your home (secure fragile items), and let them indulge their inner hunter. And who knows, maybe your cat is plotting the next great “vase takedown” as we speak! 🐾🏺

I think you are right. He/she was just playing and cats like to see things fall and hit the floor. She followed up by playing with the object. Thanks for commenting.
I have seen my cat knock objects (a pen) off my desk in order to bat them around on the floor. My attention, or lack thereof, seemed irrelevant as the cat was amusing itself; I was welcome to join in the play!
Wow again. You have a slightly unusual lifestyle but a nice one and a successful one. I love to see that. And your cats are happy. Great to know that you get on so well with your son. That is precious. Thanks for telling me about these things.
