Other causes of cat sneezing include allergies, irritants such as dust or smoke, a foreign object such as a seed lodged in the nasal passage, nasal polyps, nasal cancer, or fungal infection. The inhalation of mold, pollen, and dust is one of the most common causes of intermittent cat sneezing.
Just doing something is better than no exercise at all. Remember, 20 minutes is considered the minimum prescribed amount of exercise for one day. As your body adjusts to this level of exercise, you should increase the amount of exercise that you are doing to continue receiving the maximum benefits.
