The little male Sumatran Tiger cub, born on March 3rd to mother Bahagia at the Sacramento Zoo, is now eight weeks old. ZooBorns has been reporting on the baby's birth and growth, which you can find HERE and HERE. Named CJ, the cub is now a hefty 16 pounds, has almost all of his teeth in and is very playful with mom. He is not eating solid food yet, but has shown interest by investigating Mom's meals.

The latest development is that CJ is walking!  He spends a lot of time following Mom around, exploring the den, and expanding on his his new abilities with little bouts of jumping.
