We used to have mice and rats eating the grain in the barn.
Rob wanted me to lay traps and poison. I really didn’t want to set poison with the dog and livestock (although he was putting it in between the foundation and barn siding, the animals couldn’t have reached it)
I suggested a much more natural approach. The farm up the road had 2 litters of barn kittens. He said he never had mouse problems, and offered 2 kittens.
Fluffy and Ninja came to live in our barn. I honestly don’t know if they have killed our rodents or if their presence alone deterred them.
But there hasn’t been a single hole in a grain bag for 6 months.
And as an added bonus they are very sweet and run out to the kids when they see then coming to do daily chores.
