thank you for your opinion and interesting article! Other than the poop, Pitbull seems to be doing okay maybe. He doesn't really move in his cage, and it is not interested at all in his toys, but he loves to chew on the cuttlebone. So I guess I could see the cuttlebone as the toy for now. He is also no longer fluffed up. He doesn't nap anymore like it happened 1 week ago. Last week, I would walk in his room and he would be sleeping, wake up to see what I want, and if I don't do anything and just stare, he would simply go back to sleep. Now when I go check on him, he comes to the front door, starts eating his cuttlebone, eats his food/drinks water and is observing me. I am happy he is no longer sleeping so much! But he still doesn't want to come out. It is very sad, I keep his door open all the time, yet he just sits in front of the open cage and looks outside. How will he get his exercise to be strong to fly again if he doesn't wanna come out to play?
