My 6-year-old female cat has suddenly started urinating on the beds, in our laps and on the bathroom floor. She is also licking her bottom a lot. The urine is clear and not sticky. This cat was the runt of her litter and is much smaller than the others. She is thin and seems to have a lot of gas. Her doctor has not anything wrong with her in the past. We have not had any changes in our household in over a year.
