WEST BEND, Wis. (CBS 58) -- The Shalom Wildlife Sanctuary in West Bend was found to be at fault for the deaths of two tiger cubs. This, according to a report from the United States Department of Agriculture (USDA). 

The USDA says, an inspection took place last month, just a few weeks after two cubs -- Nina and Khan -- died after falling through thin ice on a pond in their enclosure. 

The two were part of a litter of four cubs born in August. 

The USDA says the climatic conditions that morning were likely a role in the tiger cubs' death.

An inspection report says the facility failed to protect the cubs by preventing access to the pond. 

The animal sanctuary was ordered to maintain corrective actions to protect animals from unsafe weather conditions.
