Review on FELIWAY ThunderEase Cat Calming Pheromone Spray - Anxiety Relief For Travel, Vet Visits And Boarding by Bubba Baldwin

We have a male cat that started peeing on the outside of the litter box when he was 3 years old. Tried everything to get him to pee inside the box again. Then he started spraying certain areas in the house. We thought we would give this a try and within a few days he stopped spraying in the house but continues to pee outside the box so we put training pads underneath the box to catch the urine. We tried the diffusers first and they did nothing. The spray solved half of our problem. Worth buying it .
