Best Cat Repellent I've Found by J in Mich12/31/2011
A feral cat was preying on our backyard wildlife. I've tried LOTS of repellants. None worked! I tried CatStop. Now, the cat never occupies the bush where he used to spend all day scoping out his next meal; and I rarely see him in our backyard (although he occasionally sits beyond the CatStop's range and may run in to catch something, but I haven't seen that). I'd like him to run in fear of the CatStop, but it's not that effective. Seems to just be annoying enough that he generally stays away. CatStop performance is acceptable, but could have more sensors for a wider view angle and more sectors within the view angle. It also seems to be activated by the sun and moving leaves. I've replaced the battery 3x in a month because of these unwanted alarms, but I suppose they just annoy the cat that much more. It's good; the best I've found; but it's not exceptional.

These work great. I bought 3 and sold all of them. Now I need more and I need to keep at least a couple in my own backyard.
