Questions about ferals.

[Katherine1]

I was at the neighbors the other day and she was asked me if I knew that I had feral cats living in my barn. I had no idea! We live out in the country and you can see my barn from both my neighbor and my house (from the back windows). Our barn is quite a bit aways from our house and right now we are not really using it for anything so there has no need for any of the family to go back there especially with all the snow we have had this winter. Our boarder said that he walked back there and saw a couple of them but they scattered as they saw him approaching. I had noticed that Molly has been barking more the last week or so when out on her lead but didn't think much about it since it is getting warmer and we do live in the country with racoons, skunks, squirels and such. However this morning we were eating breakfast and we looked up and there at the back door ( on the partially enclosed porch) was a cat looking in. I went to the door and it took off. It was back again this evening looking in the door again but took off when Molly discovered it looking in and barked at it. I am not sure what to do and thought that I would post here and hopefully get some suggestions. I don't know how old they are or even how big they are. The on that I did see didn't seem to be a kitten but really didn't seem to be a full grown adult cat either. I am really concerned about them having enough to eat. The only thing I have here is dog food. Do you think that it would be alright to take some dog food out to the barn for them or should I even do that? I do not know if they belong to a neighbor because our neighbors houses are not close to us except the one neighbor that told me about the cats and I know they are not hers she only has 2 dogs.
