The primate got his only taste of the outside world and he was completely spellbound, proving how isolated he is in his small enclosure. Raj's keeper told the Daily Mail he "loved to be involved" and to "imitate people".This isn't the first time Raj was filmed being gentle and loving towards his visitors. Last year, a 37-week pregnant Maisie Knight went to visit him and he kisses and rubbed her round belly in a very sweet and broody manner.[embed]https://www.youtube.com/watch?v=c3F0ZY2VzKc[/embed]These kinds of interactions with humans show that Raj craves company.If you would like more information on the treatment, living conditions and psychological effects on animals living in zoos, visit the Humane Society's website.
