Maybe it's a case of empty nest syndrome?
Kimon, an 8-year-old long-tailed monkey, has taken in a kitten as one of her own at the Bintan Island home the two share in Indonesia.
Seen in photographs taken on Sunday, Kimon keeps the cat close at hand, even grooming it and inspecting it for fleas. The furball is rarely out of the monkey's grasp, even as she makes her way around her habitat.
But Kimon is hardly the first ape to attach herself to a feline: A baboon from an Israeli petting zoo similarly adopted a stray kitten
of its own last month.
