Does a cat come when you call it? Saskatoon lion cubs named, but respond to food

SASKATOON - Maybe it's because it took almost a year to name them, but Saskatoon's lion cubs don't seem to be listening when they're called.

John Moran, manager of the Forestry Farm Park and Zoo, jokes that Nathan and Shadow are much more responsive to food.

The cubs were born last September and were officially named Thursday.

Moran says they weigh about 45 kilograms each and have adjusted well to their exhibit.

He says most zoo visitors are surprised at how much the cubs have grown since they were born last fall.

Moran says it will take awhile before the cats respond to their names.
