In the morning, when I'm home I open the run door and let the girls roam our yard for the day. Last week I found a very tiny kitten inside their run while they were not. Today the kitty is back, kinda just hanging out in the yard with the girls. They don't seem to mind her presence and I think she is just lonely. I went out to offer her some food and she ran away. Other than disease is there a reason I wouldn't want her around?
