As I mentioned above, urination is one of the ways that cats use to show their dominance and mark their territory. However, this ford is one of the less common ones and is usually correlated with elevated stress. This means that your cat is feeling anxious and is doing this behavior as a way to build their boundaries. It might also be due to some urinary tract infections. You can ease their stress by using cat pheromone diffusers like Relaxivet anti-stress formula.
