We as well love are cats living on the farm seems to attract lots of them we have three of are own and many outside cats that we feed .
My wife will capture as many as she can and bring them to the SPCA for a check up and if there healthy they are put up for adoption we probably feed about a dozen
strays at any given time about 30 pounds of cat food a month .
At least we dont have a problem with mice if they make it passed the cats they have this to contend with to make it in the house.
