Query: Actually increased cat spraying

Plug it in and the cat backs into it and SPRAYS THE THING. Wasted $45.00 on this product at Petsmart. Actually increased the spraying of the male cat I adopted from then shelter. Kitty is a fixed males -- been fixed since early kittenhood -- 4 years old now, age of adoption.My 3 grand worth of new carpet can testify. The whole house is a mess. The vet has recommended Buspar pills and/or tranqs. Was hoping to avoid that, but either we try a pill- it works -- or we haev to sadly return him to shelter. Maybe that was why he was in the shelter to begin with, poor guy. We are crushed.
