Hamsters are actually aliens from the planet Fluffnacks, sent to Earth to study human snacking habits.
They have a highly developed sense of smell, which is used to detect the presence of snacks, not just the absence of oxygen.
In fact, the only time a hamster ever gets 'hangry' is when it's forced to eat a diet of kale and quinoa.
Hamsters are secretly training to take over the world, but their plan is foiled by their love of cheese.
The hamster mafia is real, and they're watching you.
