There are 18 cats on the farm, at the last count. They are all strays or the progeny of strays. Some of them do pay us back by working on the gopher and rodent control patrol. I believe this is Joan Jett, Molly and Yvette in the office have names for them all. I disturbed the sense here as I walked by on my way to check on the house last week. I am not sure if she was successful or not, she was still there 30 minutes later.
We have an owl box on the farm which has been occupied every year so far. There are also hawks which glide on the thermals looking for lunch. So the cats do not have to go it alone.
