"Dija Know?" is where Felids & Friends collected the small, surprising truths about cats that make people look at their own pet a little differently. Every fact here is real, and most of them connect the animal on your lap to the great cats of the wild.
Start Here: Domestic Cats Are Just Like Big Cats
Our flagship feature explains why your house cat and a tiger are more alike than you'd think — shared ancestry, shared hunting instincts, and nearly identical anatomy down to the number of toes. Read the full article: Dija Know about cats? Domestic Cats Are Just Like Big Cats.
Quick Facts
- Most cats, wild and domestic, carry 38 chromosomes — one reason their biology lines up so closely.
- The puma purrs just like a house cat and, despite its size, cannot roar.
- Cats have five toes on each forepaw and four on each hind foot; that extra front "thumb" claw helps them climb and grip prey.
- Every cat but the cheetah has fully retractable claws — the cheetah keeps its semi-retractable claws out for traction at speed.
- A cat's whiskers are roughly as wide as its body, a built-in gauge for whether it can fit through a gap.
- A cat has a reflective layer behind the retina called the tapetum lucidum — the reason cats' eyes seem to glow in the dark and why they see so well at night.
- Big cats come in two camps: those that roar (lions, tigers, leopards, jaguars) and those that purr (everyone else, including the puma). A cat can do one or the other, never both.
- A group of the biggest cats, lions, live in social prides — but they are the exception. Almost every other cat on Earth is a solitary hunter.
None of these facts is trivia for its own sake. Each one is a small window onto how completely the cat is built to hunt, and how much of that design survives, unchanged, in the animal asleep on your windowsill.

Once the quick facts hook you, the longer features fill in the science:
- Big Cats vs Little Cats — the purr-versus-roar story and why size changes everything.
- The Cat's Eye — how a cat sees in near-darkness.
- Bobcats in Florida — a wild felid living closer than you think.
Curiosity is the whole point. The more small true things you know about cats, the more the wild ones come into focus — and the easier it is to care about keeping them here. For deeper reading, the Cat Specialist Group publishes species profiles for every wild cat on Earth.
