(c) the animal is so severely injured, so diseased or in such a physical condition that it is necessary that the animal be provided with veterinary treatment and the animal is not being provided with that treatment, or
(d) the animal is so severely injured, so diseased or in such a physical condition that it is cruel to keep it alive, and the animal is not about to be destroyed, or is about to be destroyed in a manner that will inflict unnecessary pain on the animal.
