The natural food chain is causing problems at the Dallas Zoo, where a wild bobcat has killed two of the zoo's African dwarf antelopes, officials said.
Traps have been set and zoo employees using tranquilizer dart guns have been prowling the grounds since the bobcat was spotted near the remains of two dik-dik antelopes at daybreak recently.
The bobcat has been seen several times since the attack.
Zoo spokeswoman Pam Deutsch said the facility still has eight dik-dik, which are named for the sound they make when alarmed. The short-horned creatures stand less than 2 feet tall at the shoulder and weigh less than half as much as an adult bobcat's 20 to 30 pounds.
