3-year-old Malayan tiger Seri killed 6-year-old Wzui at about 4 p.m. on Thursday in an enclosure at El Paso Zoo.
Zookeepers had not observed any signs of aggression leeding up to the attack, and that the two tigers had been seen playing affectionately at the exhibit earlier in the day.
However, zoo authorities reported what they called a "tiger love triangle" between Seri, Wzui and 15-year-old female called Meli, who was transferred to El Paso from a zoo in California.
The male tiger Wzui likes both females, but the two females don't like each other.
There's more ways than one to kill a cat, but females are horrible in any world, indeed...(^o^;)
