My cat's hiding a lot and won't eat or drink. How long without eating or drinking should I worry if she isn't urinating either?

Over the past couple of days, my cat has been hiding more than usual, and she hasn’t touched her food or water bowl. I'm becoming really concerned because she hasn't used her litter box to urinate either. How long can she go without eating, drinking, or urinating before it becomes a serious issue?

Answer

Your cat's change in behavior, including hiding, not eating, drinking, or using the litter box, is concerning and may indicate a medical issue that needs prompt attention.

  • Cats not eating or drinking can become dehydrated quickly.
  • Lack of urination can be a serious issue indicating possible urinary blockage or other health problems.
  • Early intervention can prevent more serious health issues.

Cats often hide when they are unwell, so these signs are important to address quickly. Cats can rapidly become dehydrated without water, and not eating can cause hepatic lipidosis (fatty liver syndrome), which can be life-threatening. Additionally, not urinating can be indicative of a blockage, especially in male cats, and is considered an emergency. Generally, cats should not go more than 24 hours without eating, drinking, or urinating. We recommend seeking veterinary care promptly to ensure your cat receives the necessary treatment.

If this is an emergency, please seek immediate veterinary care.
