Sumatran Tigers have dark dense fur with narrower stripes than other species, giving them the perfect camouflage to mimic light reflection on the forest floor. Berani, a male, born March 6, 2008, is a laid back tiger, but will occasionally act aggressively toward his keepers. His favorite enrichment is a plastic barrel hung in his night house. He likes to stand up and bang it around, bite and claw it. We recently had to replace it because he had caused so much damage shredding the plastic that it was no longer safe for him to use. He is also fond of branches that other animals have rubbed on.
