There (be) many cases in which animals
(take in) cubs that (not belong) to them, or
even their species, like this adorable little
pig. But I (never see) a monkey taking so
well to a couple of tiger cubs before.
After Hurricane Hannah (ravage) the
state of South Carolina, the tigers of one of
the zoos (start) acting very aggressive and
were considered a danger to their young. So
these two white tiger cubs were separated
from their mother and (adopt) by a 2-yearold
chimpanzee. As you (can) see from the photo he really (take)
parenting seriously. I wonder how their relationship (develop)…
