Recently, Houston Zoo keepers gave Baylor and Tupelo a big kiddie pool. Now that Baylor weighs more than 1100 pounds and Tupelo weighs more than 600 pounds, the small, inflatable pools do not last longer than 5 minutes without getting popped. The babies now get a family size pool which is 120 inches in length and holds both calves. It is a lot more durable. This size pool lasts for about 5 uses before it has to be replaced. Playing in the pool is a fun enrichment activity for the babies and the pool is given to them when the weather allows.
