This will quickly lead to ulcers on its rear end and the ulcers are difficult to treat. If ulcers occur, use Bactine spray or antibacterial ointment and remove the source of trouble. If there is no immediate improvement, seek professional help. I have found the pottos' favorite fruits are loquats and mangoes. They will skillfully track and catch a moth heard fluttering on the other side of the room.
Pottos are prone to dental problems.
They learn what to eat from their mothers so a good diet, including dry food, should be offered during this sensitive period. Citrus fruits are not favorites, but they do like kiwi fruit. Considering the number of pottos available in the 1980's and the fact that with good care they can live more than 15 years, it is surprising there are so few around. Perhaps they didn't survive long due to improper diet and maintenance. Because they sleep in the top of trees, they may need sunshine even though they are active only at night.
