Yes cats can and will mate with siblings-they don't make choices about their reproduction like humans do, there's only hormones and instinct. Any kittens produced from a brother/sister pairing will be at greatly elevated risk for genetic deformities and diseases. Get the cats fixed and avoid the problem altogether.
To make matters more chaotic -- and noisy -- female cats also vocalize out to males. When queen cats are in the midst of their heat cycles, they also try to promote their mating readiness to males. Like with tomcats, the yowling sounds are often persistent and loud -- and usually nocturnal too, though not always.
