Maybe it's not the Bitter Apple that's causing Beanie's apparent constipation. Maybe he is actually ingesting too much of Nosmo's fur during their rough play. Our very first ferret, Odie, who started all this ferret stuff with us nearly 9 years ago, had several bouts with constipation due to fur in his stomach. It made him very sick. After I gave him Laxatone and he was able to go, I saw that it was dry and filled with fur. You might try giving Beanie a bit of Laxatone or Petromalt a couple of times a week and see if that alleviates the constipation problem. Check out his droppings right after that to see if they contain fur. Constipation can be very, very serious in ferrets, so you want to try to keep it from happening in the first place.
