Animals who have not urinated in 18-24 hours are considered a medical emergency and should be seen by a veterinarian immediately. Urinary blockage (urethral obstruction) is particularly common in male cats but can be experienced by any animal. Urethral obstructions are life-threatening if they are not treated immediately.

For pets who have not defecated, contact your veterinarian for further instruction. Some cases may be simple constipation, but if your pet has not defecated because they are not eating, for example, an evaluation may be warranted.
