We've headlined this 'Hamster Climbs Stairs', but a more accurate description might be 'Hamster Vs Stairs'.
WATCH! As little Hammy battles against the staircase. GASP! As he attempts to cling onto each step. LAUGH! At how funny animals are. Aww.
Hammy's problem, of course, is that he's not behaving like a natural hamster in the wild - frolicking in a field, eating lettuce, or going round and round in a wheel - but is, in fact, attempting to do something that humans do. And as we all know, there's nothing funnier than that...
