Over the past week, first responders have carried thousands of injured animals out of the ashes to emergency veterinary hospitals. Many of them were found sitting in the smouldering rubble of their former homes, burned and dazed.At VCA Valley Oak Veterinary Centre in Chico, California, the staff cancelled regular appointments so doctors could focus on wildfire victims. Hundreds of pets, mostly cats, were dropped off over the course of five days.We've run out of space," said Daniel Gebhart, the co-medical director at Valley Oak. He had about 20 animals under his care on Wednesday. Injuries include smoke inhalation, dehydration and severe burns, Mr Gebhart said. The animals in the worst condition, with third-degree burns all over their bodies, have had to be euthanised. Fortunately, the vast majority of the animals that have come through Valley Oak's door have been saved, Mr Gebhart said.Veterinarians administer pain medication to the burn victims immediately. They are given fluids, antibiotics and oxygen depending on the nature of the wound."Once they're stable, we can debride and clean the wounds," Mr Gebhart said. "We've been so emotional the past five days. It's so sad to see; they're in such terrible pain."
