Hello! I hope someone out there that has experience can offer me some advice. I have a small stray colony of 6 abandoned cats in an enclosure we built for them in my backyard. The time has come to release them, as they have been in there for almost 4 weeks. As expected, I am afraid to open the door to let them out. Is there a protocol for this? Best time of day? All at once, or one at a time? We are not far from their old neighborhood, and I am naturally worried they will try to return. The only thing I am sure of is that I will need a lot of tissues!
