Do you know how is constructed the cubbing den for polar bears in Leningrad, especially how is it insulated? I know this zoo is one of most successfull places in polar bear breeding for decades (maybe the best in the world?).
And second question - Prague tries to get a new breeding male from Leningrad (he should be 6 years old). Do you know his name? And if he is related to a male Alik (born 1977 in Leningrad), that was sent to Prague in 1978 and his daughter still lives here.
Snowleopard: Miniaturezoo954 is right - in Russia it's like a palace and it's almost whole in the picture - land, at least.
Jana: sorry, but I don't know anything about female's den. And I don't know the name of 6 years old male (you can see him on one of the pictures in the cage). But I'm sure he's not a relative to Alik, because his father Menshikov is wildborn in late 1980th, and mother Uslada is from Moscow zoo.
