Guinea Pig Warning Signs

In short

Guinea pigs hide illness and can deteriorate quickly, and a guinea pig that stops eating is urgent. This page helps you recognise warning signs and escalate — it does not diagnose or treat. Know a guinea-pig-savvy veterinarian before you need one, and call promptly when something seems wrong.

How to act

  • If your guinea pig stops eating or drinking, contact a vet promptly — they should eat almost constantly.
  • If you are unsure, call; telephone triage helps you decide.
  • Know your guinea pig's normal eating, droppings, and behaviour so changes stand out.
  • Keep a guinea-pig-savvy vet and an emergency option saved in advance.

Warning signs that warrant prompt veterinary contact

This list is not exhaustive, and signs can have many causes. Any of these warrants prompt veterinary contact.

  • Not eating or drinking — urgent in guinea pigs.
  • Laboured or noisy breathing, or discharge from eyes or nose.
  • Severe or watery diarrhoea, or a soiled rear.
  • Drooling, weight loss, or signs of dental trouble.
  • Weakness, collapse, injury, suspected poisoning, or rapid worsening.

What not to assume

  • Do not adopt a "wait and see" approach — guinea pigs can decline quickly.
  • Do not try to diagnose or treat at home; many remedies are unsafe.
  • Do not assume a quiet guinea pig is well — they hide illness.
  • Do not give any medication unless a veterinarian prescribes it.

When to contact a veterinarian

Guinea pigs need near-constant food intake and hide illness well. Do not use this page to diagnose — find a guinea-pig-savvy veterinarian in advance.

  • Not eating or drinking — guinea pigs should eat almost constantly, so this is urgent.
  • Laboured or noisy breathing, or discharge from the eyes or nose.
  • Severe or watery diarrhoea, or a soiled rear.
  • Weakness, collapse, injury, or suspected poisoning.
  • Any rapid worsening — contact a veterinarian promptly.

Guinea Pig Warning Signs — Frequently Asked Questions

Why is a guinea pig not eating an emergency?
Guinea pigs need to eat almost constantly to keep their digestive system working. A loss of appetite can quickly become dangerous, so contact a guinea-pig-savvy veterinarian promptly rather than waiting.
Can I treat my guinea pig at home?
No. Home treatment is not appropriate for these signs, and many remedies are unsafe. Contact a guinea-pig-savvy veterinarian instead of waiting or trying remedies.
How do I find a guinea pig vet?
Identify a guinea-pig-savvy veterinarian before you need one, and save an emergency option. Calling ahead in a crisis lets the clinic prepare for your arrival.
