I have a $10,000 generator in my yard. Last winter the mice got into it and tore apart the air filter for use as nesting material. Lat winter I was in Aruba when we lost our power and the generator would not turn on because the filter was gone. I called several electricians and they did not have a good solution. I called the generator manufacturer and they did not have a good solution. I called several major pest control companies and their solutions did not work. I finally called Catseye and they had the solution. Now my generator is encaged within screening material that is impervious to the mice. It has doors and a roofing panel all of which can be opened to gain access to the generator to service it. Catseye had the solution and they built it and installed it in a professional way. They earned 5 stars.
