This is a set of three replacement sprays for cat repellent. The first one seemed to be quite effective, as cats stopped coming around, so I kept the remaining two at home without using them. They have been stored for about a year and a half. The plastic bags are unopened and the items are unused. I've tried various cat repellents, but I personally think this one worked the best. If you're having trouble with cats, would you like to try it?
