National Organic Program (NOP) standards state that producers must use management practices for pest control.
When our inspector asked us how we plan to control pests, Bill and I asked, "are barn cats allowed?" She said absolutely.
We don't have an issue with an overload of barn pests - although we don't have any feed supplied in our barn to draw them yet - when our neighbor's cat (who is a skilled mouser) had a litter we thought it would be a good time to get some kittens. We took the whole litter: 3 males, 1 female. We had them neutered/spayed and vaccinated under the "barn cat sterilization program" at the local animal hospital.

This cat has professor-like patches on his elbows.)

Mr. White - paws crossed, doesn't care
Thomas - well (can you tell ?) he's the alpha
They are 7 months old, friendly, and enjoyable to have around. 3 Flat Acres first official animals!
