Q. My cat urinate all over the house
A. Firstly you need to rule out a medical problem causing it. If not it maybe that something has changed in the environment either a new cat in the area or something in the house. New member of the family, New furniture. If you can find the cause it is easier to sort out. You can try pheromone diffusers if it is stress related. It is important not to clean the areas with anything other than water as the smell of the chemicals can make them urinate on the areas again if the find the smell threatening.
