Will Mouse Blocker affect dogs or cats?

MouseBlocker is Safe for Animals!

Mouse Blocker Units are 500 times louder than any other unit on the market today (trust us we tested them all) and on the highest settings most humans can hear the sounds emitted as will some household pets like cats and dogs. The sounds WILL NOT harm them in any way you will just notice the animals will leave the area the unit is located and if under the hood of your vehicle the sounds for the most part will be contained in the engine compartment anyways.
