Hello everyone. Well the title pretty much sums it up. I have a problem with an outside cat (not mine) spraying on our deck doors. It drives our cats crazy and I don't know how to get this to stop. We've Used Boundary cat repellent to stop him from doing it but it's to no avail. I clean up what I do find with Natures Miracle but apparently the smell still lingers since my littlest Calico keeps crying at the door now. She's all upset and I'm sure the others won't be to happy when they smell it as well. I'm also concerned with this other cat having diseases since I don't know who owns him or if he's even owned..Can someone please help me keep him away? Hubby is getting frustrated and wants him gone, like yesterday. But I'd hate to take someones pet to the shelter because he's spraying, I mean it's not his fault really right? I just want to keep him away from the house. Since repellent isn't working, can someone PLEASE help me find a solution?
