EL PASO, Texas (AP) - Texas zoo officials say the killing of a rare Malayan tiger by his mate caught the zoo completely by surprise and that there were no warning signs.
    
El Paso Zoo director Steve Marshal said Friday that 3-year-old Seri and 6-year-old Wzui (wah-ZOO'-ee) seemed to have bonded during their two-and-a-half months together and had even mated.
    
He says the animals were seen playing and being affectionate with one another on Thursday just hours before Seri bit down on Wzui's neck and choked him to death.
    
Minnesota Zoo conservation director Tara Harris says tigers sometimes fight but very rarely kill one another. She says it's even rarer that a female would kill a male.
    
Marshal says the zoo hopes to find another suitable mate for Seri soon.
