Please don't use this address for pet emergencies. I'm not a veterinarian and can't advise on your pet's health. If your pet may be sick, injured or poisoned, call your veterinarian or an emergency animal hospital now. For a possible poisoning in the US you can also call the ASPCA Animal Poison Control Center at (888) 426-4435(a consultation fee may apply).
