Have Reptile Veterinary Questions? Ask a Reptile Expert.
Hi this is Dr. Hill. Unfortunately, it sounds like your gecko is gasping for air. Reptiles will do this when they have a severe respiratory infection. You need to take him to your veterinarian or local emergency clinic right away to see if they can save him. He will need oxygen, fluid therapy and antibiotics.
Please let me know what you find out with your gecko.
