This orangutan is just as touchy-feely as people usually are with a pregnant lady's body, so why is it kept in a zoo?

Animals!!! You break my freaking heart. I know the issues around zoos and conservation are complicated, but just look at this sweetheart. Why is he caged? Like, I know at this point if he were released randomly into the city it would be very dangerous. But in general, animals don't belong in captivity. Except my cat.

This orangutan is living in Colchester Zoo and this is what the filmographer says:

Me and my 37 week pregnant partner visited Colchester Zoo on 13/07/2015 and was amazed when we visited Rajang the Orangutan that very quickly become fixated with her belly as she is heavily pregnant and before long he was trying to kiss my partners belly through the glass. I put my belly too the glass and got a dirty look then when I placed my hand on the he tryed to push my hand away my partner returned her belly to the glass and Rajang touched and kissed her belly again through the glass. Truly a special animal that has touched our hearts.
