I have 9 feral cats at Wizz Catz one of whom has a habit of spraying on some drawers that are on a work surface in the kitchen. She is intolerant of all the other cats in the rescue so she has to have ‘time out’ on her own where she has a habit of spraying everywhere. I put the atomiser on top of the cupboard so it sprays down on to the work surface. Set it for once every 30mins to start off with, now once every 60mins – so far so good, no spraying on the drawers! I have a plug-in in her room, and use the spray around the cat pen. Really impressed with Pet Remedy as it has worked where others have failed. Thank you
