Having a fear of rats is completely normal... but perhaps not if you are a cat.
A hilarious video filmed in Tianjin in northeastern China shows a terrified moggy being chased by a rat.
The rodent scurries towards the cat as the cat runs sideways in fear.
It is chased round in a circle as it desperately tries to leap away from the rat.
The feline leaps up on the pavement in the hopes of escaping but the critter is nothing if not perseverant.
Comically - for the audience, not so much the cat - the moggy kicks up its hind legs in an attempt to avoid contact, before the video ends.
To be fair to the cat, it is only relatively small itself and the rodent is both sizable and speedy, but it certainly doesn't have a career in successful rat catching any time soon.
Mice are the standard prey for cats as their small size limits the possibility of counterattack, whereas rats live up the the phrase 'fight like a cornered rat' and can deliver a painful bite when they fight back.
Natural born hunters, cats also sometimes attack birds and rabbits.
Unlike most animals, felines are in fact 'obligatory carnivores', according to biologists, as they require meat to boost their taurine levels, without which they cannot live.
Taurine is an essential amino-acid - one of the building blocks of proteins. Cats' bodies do not produce enough for survival without feeding.
Interestingly it has been found that rather than hungry cats make the best pest controllers, it is in fact the well-fed moggies who make the best hunters, as many farmers have discovered.
