The cubs are round and solid, and the people who follow this family keep saying the same thing. They look healthy. They also look big, so big that one fan figured she must need an enormous den to fit them all.

At 24, Grizzly 399 is getting on in years for a grizzly bear.

Over her 24 years, 399 has had 17 cubs. Four at a time is a lot for any mother, and she makes it look easy.
