Have you ever watched your 10-pound cat try to intimidate a 50-pound dog? Or noticed how they show up for dinner at 5:00 PM sharp, even though they can't read a clock?
It makes you wonder: What is actually going on in that furry head?
Cats live in the same house as us, but they perceive a completely different reality. They don't see us as owners, they don't see themselves as pets, and they certainly don't think they are small. Today, we are answering four of the most existential questions about feline intelligence.
Key Takeaways
- Size: Cats likely do not realize they are small. Their "fight or flight" instinct often chooses "fight" regardless of the opponent's size.
- Time: They don't know "hours," but they are masters of predicting events based on sunlight and your routine.
- Humans: They probably see us as "clumsy, giant cats" rather than a separate species.
- Death: They may not understand the concept of mortality, but they definitely feel the pain of absence and loss.
1. Do Cats Know They Are Small?
If you put a mirror in front of a cat, they don't recognize themselves. They think it is another cat. This suggests they lack a certain level of self-awareness that humans and some apes have.
But more importantly, their behavior suggests they have a "Napoleon Complex."
In the wild, showing fear is a death sentence. When a cat puffs up its tail, arches its back, and turns sideways, it is trying to hack its own biology to look bigger. Behaviorists believe that in that moment, the cat genuinely feels capable of taking on a threat ten times its size. They don't calculate weight classes; they calculate confidence.
So no, your cat doesn't know they are small. In their head, they are the biggest tiger in the room.
2. Do Cats Know What Time It Is?
Your cat doesn't know it is "5:00 PM," but they know it is "Dinner Time." How?
Cats are experts at Interval Timing. Their brains are wired to track the duration between events.
- Internal Biology: Their hunger hormones (ghrelin) spike at consistent times.
- Environmental Cues: They notice things you ignore. The specific angle of the sun on the floor, the sound of the mail carrier, or the hum of your car pulling into the driveway.
If you are late feeding them, they aren't judging you for being unpunctual. They are confused because the reliable sequence of their universe (Sun down -> Car sound -> Food) has been broken.

3. Do They Know We Are Not Cats?
Dogs act differently around humans than they do around other dogs. They shift their behavior to accommodate us.
Cats? Not so much.
John Bradshaw, a famous expert on cat behavior, suggests that cats treat humans like other cats.
- They rub their heads on us (scent marking).
- They knead us (a kitten behavior toward their mother).
- They bring us "gifts" (teaching us to hunt).
To your cat, you aren't a different species. You are likely just a giant, clumsy, hairless cat who is terrible at hunting but excellent at opening cans. It is actually a huge compliment. They accepted you into their tribe as an equal (or perhaps a slightly inferior member).

4. Do Cats Understand Death?
This is the saddest question, but one of the most common. When a companion pet dies, does the remaining cat understand?
They might not grasp the abstract concept of "death" or an afterlife, but they absolutely understand absence.
Cats form deep social bonds. When a companion disappears, the survivor often shows classic signs of grief:
- Searching the house and calling out (yowling).
- Eating less or sleeping more.
- Becoming clingy or withdrawn.
The scent of the missing friend fades, and the routine changes. This disruption causes genuine anxiety and sadness. They know their friend is gone, and they miss them.

Final Thoughts
We often project our own human feelings onto our cats. We think they are spiteful, or guilty, or judgmental.
But the truth is simpler and sweeter. They live in a world of instinct, sensory patterns, and immediate needs. They might not know their size or can't read a calendar, but they know the most important thing of all: You are their family (even if you are a weirdly large cat).
Frequently Asked Questions
Yes, mostly. Studies show cats can distinguish their names from other words. However, unlike dogs, they often choose to ignore you if there is nothing in it for them.
They likely don't understand 'sadness' as a complex emotion, but they are masters of reading body language. If you are still and quiet (depressed), they may approach you for warmth or comfort, which feels like empathy.
No. Most cats see the reflection as a stranger. They might attack it, sniff it, or simply ignore it because it has no scent.
