His screen is more like a window screen. I normally have the top off though, as he is not at risk of climbing out. As for the tail rot, his appointment is on Tuesday to have his tail partially amputated. I will look into the Repashy bug pies as that might be better than the chicken and squash baby food. I really appreciate all of the suggestions and just hope he gets better. He’s such a sweetheart. I just hate to see him in such bad shape.
