Two female gibbons and a tapir were recently re-homed at London zoo and a couple of snow leopards are next in line to leave Kaliningrad.
The zoo has a troubled history.
It was founded in 1896, but there were only four animals left at the zoo by the end of the Second World War.
In the following years, it built up a collection of 370 species, but now it's in decline once again.
However, the local people are determined to help the animals - the keepers often turn up at work to find that food has been thrown over the fence.
