(i) food and water of sufficient quantity and quality to sustain the animal's normal health;
(ii) minimum protection for the animal from adverse weather conditions, with consideration given to the species;
(iii) in cases of immediate, obvious, serious illness or injury, licensed veterinary or other appropriate medical care;
(d) abandoning any helpless animal or abandoning any animal on any highway, railroad, or in any other place where it may suffer injury, hunger, or exposure or become a public charge; or
