My neighbors have cats. I am allergic to them. I have couches outside which I used to enjoy sitting on to watch the kids while they play. I could take a notebook and write away while they enjoyed themselves, and all was well. Except that the neighbors' cats have taken to sitting on my couch, so now I cannot. I have spoken to them, and they don't seem to care that I cannot sit on my own couch, so I am forced to turn to other measures of control. Has anyone had any experience with that pet repulsion spray? Like 'Off!'? I am afraid of it leaving a residue which would be unpleasant to sit on. Or, has anyone had any experience cleaning the cat dander from fabric? I am clueless. Thanks.
