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.
Some female cats will only display their heat behaviours in the presence of a male cat (i.e. they do not display for non-cats, including their owners). Owners of such cats might never see their female cat show the signs of estrus if she is never allowed to come into the vicinity of a male cat.
