Section 910.130 - Feeding

(A) Dogs and cats shall be fed at least once each day except that more frequent feedings may be needed in special circumstances where nutritional supplement is required (e.g., pregnancy and lactation). The food shall be free from contamination, wholesome, palatable, and of sufficient quantity and nutritive value to meet the normal daily requirements for the condition and size of the dog or cat.

(B) Food receptacles shall be accessible to all dogs or cats and shall be located so as to minimize contamination by excreta. Feeding pans shall be durable and kept clean and they must be constructed of material that is non-toxic and not rusted or corroded. The food receptacles shall be sanitized at least once every two weeks. Disposable food receptacles may be used but must be discarded after each feeding. Self-feeders may be used for the feeding of dry food, and they shall be sanitized regularly to prevent molding, deterioration, or caking of feed.

(C) If potable water is not accessible to the dogs and cats at all times, it shall be offered to such animals at least twice daily for periods of not less than one hour, except as might otherwise be required to provide adequate veterinary care. Watering receptacles shall be kept clean and shall be sanitized at least once every two weeks and be constructed of non-toxic materials that are not rusted or corroded.
