BORYSEW, Poland (AP) — Seven rare white wild cats — four lions and three tigers — have been born in the past week in a private zoo in central Poland.

The lions were born on Sunday at the Zoo Safari in Borysew and are doing well under the care of their mother, 5-year-old Azira. They are the fourth litter for Azira and 7-year-old Sahim. There are at most only a few hundred white lions in the world.

Head of the zoo Andrzej Pabich said the genders of the cubs was unknown because keepers have not touched them yet.

On Thursday, a white tiger also gave birth at the zoo, and Pabich believes there are three cubs.
