I just purchased the Scat Mat Power Adapter and hooked it into my Scat Mat that was previously run by a 9-volt battery. The power adapter keeps activating the Scat Mat constantly. There is no break between activations. Another review on this site had the same problem. There are numerous complaints on Amazon's web site as well about this power adapter problem.
I know it's the power adapter because as soon as I switch out the adapter for the battery, it works fine.
Other customers have had both the power adapter and the controller replaced numerous times without success. There has to be a glitch in the electronics of the controller that causes this to happen.
I don't see any way to get around this problem without a redesign of the controller.
