A Swedish woman's pet cats are secretly two ninja fighters.
Mats Hamnas has snapped the fluffy felines scrapping at the bottom of her garden and performing a series of moves which look uncannily like martial arts moves.
However, Tabby cat Muffi and her furry acquaintance Tiger are apparently actually the best of friends and only indulge in their vicious antics for fun.
Mats, from Helsingborg, said: "Muffi and Tiger actually get on really well, but when you see them in these shots they look like a pair of ninjas attacking each other.
"It's amazing how they move through the air and the expressions they have are priceless.
"When the fur has stopped flying they all cuddle up together in the house and the days fighting is forgotten."
