I would like to lend a hand, but anatomically that is wrong.
Now it's time to get serious. If he is old, then it is common for feet to dry out, lose traction, or fall off. It can help to keep him well hydrated during his senior weeks/months.
thanks... yes he is old and i have been misting. i think maybe the eyesight is gone as well because i have to hand feed him. he looks comfortable..in that he is still climbing and eating well. thanks again now i know about the feet!
Sally -- My aging T. sinensis, Nikki, just gave up one of her back feet two days ago. Like, yours, she's slowing down slightly but her eyesight is good for now. Definitely an indication of aging. Checking around for prosthetics, but no luck so far. When I brought her in to CVS for advice the clerks just ran out of the store shrieking. Really weird employees.
