Some background first. I live in a suburban neighborhood. There are all sorts of cats about, some free roaming, some pets that wander, some feral. I figure the pets are the ones who wander and visit during the day. The ferals are likely the visitors at dusk and throughout the night. The outside camera captures the images so it is easy to determine the frequency of visits, time of day and the identity. I have no idea where they go for shelter but would like to leave out one of those do it yourself shelters for the ferals. How do you entice the ferals to use the shelter once it is there? For now, an orange feral appears around midnight or just after sunrise, the visits are determined by the hissing at the window from the inside cats. He/she will wait for food, eat and quickly depart. This cat seems to be less fearful with me to the point that it will accept food off of a hand held spoon so I figure why not make the effort. Any thoughts?
