There are 6 or 7 cages(sorry i dont' remember).
First and sixth/seventh cage, is the biggest, and live there De Brazza's monkeys(first cage) and red ruffed lemurs(sixth/seventh cage).
In others cages live emperor tamarins, cottontop tamarins and common marmosets. One or two cage, are empty, but in the future there will be live, others species of marmosets and tamarins. On the other side Moneky house, there is 6 outside cage. But in this moment, this side is under renovation. In the future, there will be live tamarins and marmosets.
