Toronto Zoo’s giant panda cubs continue to do very well and have recently been moved to a larger incubator as they have outgrown their first one. The giant panda keepers and Chinese experts continue to twin-swap the cubs with Er Shun and as they grow, and both cubs are being supplemented with formula. The only time the cubs are not with mom is when she is eating bamboo. Since Er Shun is a lactating mother, staff have been very focused on increasing her bamboo intake which is very important to maintain her milk production.
