I have a 4 month old little guy. I rescued him while his eyes were opened and well alert. I placed him in a cage with his foster brother which I had rescued while his eyes were closed. 4 months later I will call him eyes opened has become angry and growling. I placed him in my outdoor cage. I would put closed eyes in with him,yet he wants out and does not want any part of him any more. They were together for 4 months but open eyes changed. I believe he's ready for a soft release,but here in NY it's winter. He has a huge outdoor cage always replete with food,is it a good idea to do so at this time?
