One of our fruit bats has only one leg, and until recently its handicap did not seem to affect its daily life.  Lately, however, for some unknown reason, his toes began to straighten, making it difficult for him to hang from the ceiling, eat and perform other behaviours. In order to ease his life, the vets Dr Maya Weinberg and Dr Ron Elazari-Volcani built him artificial claws made of epoxy putty, as you can see in the photos.
