I have a 29" bp, who seems to be losing interest in food. Lately, he has been very picky of how he strikes his food. If the right situation in the right place, doesn't occur, he loses interest, and tries to get out of his feeding box. Could this be signs of fasting? And while I'm on the subject, at what size do fasting occur, and does it occur more than once? I fed him today, which was the 8th day after his his previous feeding. It took me 2 tries before before he actually when for it.
