Due to the other review, I have decided for this shock mat. Also I have two cats and one of them "drumming" night at the bedroom door. Even after a night feeding, it can happen again, because our cats are very affectionate. Love of animals or not .. the sleep I need rest; Finally, you have to recover from work and always get up early. The mat can be via AC adapter (included here) or 9V battery (not included) to operate. It sets the tone, shock and sound + shock mode. That with the sound I have so far not tried because it is beeping, making it audible for people - at night not a good idea.
Both cats were exactly once stepped on the mat and after that never again. Presumably, you can look for the battery life for many months still deter energized. In any case, since the rest. In self-test you have to say that the effect is decent .. there should even large dogs flee.
A star I have to deduct as me you finish, especially the mounting of the control module on the mat, for the price is not quite appropriate. I do not values from a cheap product, but it could be better processed. The product is washable, but not waterproof.
