Yesterday when we went out for our ramble (the same day we discovered the GHO), the dogs had been very antsy about getting out of the house and went right to the old shop/garage that is close to the house. Later I discovered the reason. I saw a shape against the dying light and when I went around to the other side I found a cat up in the shop 'attic' watching me through the copious spaces in the ramshackle old building's shake roof.
It didn't seem particularly alarmed and I chatted at it for a few minutes. I'm not really keen on having cats around, but if they are pulling their end and stay out of the way of the dogs (and do not use the garden as a sandbox) I try to be tolerant. I have no idea where they come from, but they rarely stay long. Eventually the coyotes get them.
By the way, that old dilapidated, dirt-floor shop building, about 15x20', is said to have been the first building on the place. The original homesteaders lived in it for the first two years while they were proving up the place. So says their grandson. This would have been about 1913. Those would have been some hard, hard winters.
