What does hiding and not eating mean?
Hiding and skipping meals means a cat feels unwell, and cats hide serious disease well. One missed meal with normal litter-box habits can be watched for a few hours. A male cat who strains, or a cat who will not move, needs a clinic now.
A cat who skips more than a meal or hides when they are usually social should see a veterinarian within 12–24 hours. Overweight cats can develop hepatic lipidosis if anorexia continues. This is a triage guide, not a diagnosis for the animal in front of you.
What are common causes?
- Pain, nausea, or fever
- Dental disease or a foreign body
- Urinary obstruction
- Early liver or kidney illness
What should I check at home?
Use this checklist once, then stop if handling increases distress or breathing worsens. Breathing rate, gum color, and appetite are the checks that change the plan, and a missed meal is more urgent in a bird or rabbit than the same gap in a dog. Write down what you see, including when the sign started, before you call.
- Note the last full meal and whether water intake changed.
- Check the litter box for urine and stool.
- Look at gum color and breathing effort without dragging them out roughly.
- Scan for lilies, string, or a medicine bottle they could have reached.
When is this an emergency?
- They strain to urinate, vomit repeatedly, or have a painful belly.
- Gums are pale or yellow, or they collapse.
- An overweight cat has not eaten for much of a day.
- You saw string, a lily, or a toxin.
