Speculations are being thrown around that Tatiana the tiger was "underfed," possibly urging her to go on a fatal eating binge last Christmas. It seems that when Tatiana arrived at the SF Zoo in December 2005, she came in at a normal 292 pounds. But when she was killed by the SFPD last December, she weighed in at a pin-thin 242 pounds. (No word yet as to whether or not she was cutting herself as well.) Some "experts outside the zoo" are wondering if she was getting enough to eat, which might have prompted the tiger to mistake Carlos Sousa Jr. and the brothers Dhaliwal as big, imaginary mutton chops.
