Badgers are the wildlife reservoir for Mycobacterium bovis in the UK; the badgers carry the bacteria in their respiratory tracts and sneeze/cough/hack the bacteria over the cow's food/water/pasture. When the cows come by and inhale over the bacteria, the TB bacteria are pulled into the cow's lungs and create an infection.
Like all cats they will sneeze if there is something like dust irritating their nose or they have a respiratory infection.
The respiratory system, including the nose, pharynx, trachea, main bronchus, bronchi, broncioles, and aveoli have cilia and produce mucous that can make us cough and sneeze when bacteria, pathogens, dust or other particles try to invade the respiratory tract. Sometimes, the body can go into hyperdrive on the production of mucous, causing a chronic cough even without any invader or irritant.
The respiratory system has a number of nonspecific defenses against disease. The hairs of the nose trap dust and pathogens. Mucus in the upper and lower respiratory system traps foreign bodies and pathogens. The cilia constantly move the mucus with this trapped material out of the system. The cough and sneeze reflexes also offer protection.
The irritation that initially triggers activity at nerve endings in the upper respiratory tract will wake you up before you actually sneeze.
One sneeze.
