I found a Luna cat on our English walnut trees a month ago, after he got through eating he was going a fast pace to the woods. I got him and put him into an old cheese ball container with cheesecloth for a lid. I added fresh walnut leaves everyday and soon, a cocoon appeared. I am in southeast Ohio the temps have dropped at night to 40-50 with up to the 90 s during the day. It’s been over three weeks now and if I gently shake the cocoon there is movement inside. What do Ido now? Bring him in at night?
