Authorities in Dallas say a fire that broke out at a shopping center has killed more than 500 animals, most of which were small birds. A Dallas Fire-Rescue spokesperson says in a statement that the 579 animals in the pet shop at Plaza Latina in Northwest Dallas died from smoke inhalation Friday morning. The flames from the fire never reached the animals. Chickens, hamsters, two dogs and two cats also died. The two-alarm fire took about two hours and as many as 45 firefighters to extinguish around 11 a.m. The cause of the fire has not been determined and is being investigated.
