Dawn and dusk provide the best opportunities to spot these cats as they hunt out their main prey, rabbits.
They are predominantly nocturnal, especially in the summer months when temperatures reach over 40C.
They are the masters of disguise, their coats allowing them to blend in, remaining undetected for hours despite sitting out in the open.
