He is adorable! Do you have access to a cage at all? I keep my new ferals in cages with sheets covering everything but the front door. This gives them a sense of security, and makes it sooo much easier to handle them! I always put the litterpan and food right by the door until I can gauge the temperment. I have several large cotton laundry bags with cinch cords in which I can contain the kitties, and get them in a carrier or trap to take them to the vets. He looks easily 6 months! Not an easy age to socialize, but I have done it. Are there more in the litter or just him?
