Health Risks of Being Lost

A cat living outdoors — especially one unaccustomed to it — faces significant health threats. Dehydration, malnutrition, exposure, and injuries from fights or traffic are the most common concerns. If you've found a stray cat, a veterinary check-up should be a priority.

Dehydration

Cats obtain much of their water from food. A cat that hasn't eaten for 24–48 hours is likely dehydrated. Signs include sunken eyes, dry gums, and skin that doesn't spring back when gently pinched. Offer small amounts of water frequently rather than a large bowl all at once.

Malnutrition and Weight Loss

A lost cat may lose 10–15% of its body weight within the first week. Ribs and spine become prominent. Feed a found cat small, frequent meals of wet food to avoid refeeding syndrome — a dangerous condition caused by suddenly reintroducing food after a period of starvation.

Fight Wounds and Abscesses

Outdoor cats frequently get into territorial fights. Bite wounds often become abscesses — swollen, painful lumps that may rupture and drain pus. These require veterinary treatment including antibiotics and sometimes surgical drainage. Do not attempt to drain an abscess at home.

Upper Respiratory Infections

Stress weakens the immune system, making lost cats susceptible to URI. Symptoms include sneezing, nasal discharge, red eyes, and lethargy. While mild cases may resolve on their own, severe infections require antibiotics from a vet.

Fleas, Ticks, and Ear Mites

Almost every outdoor cat carries parasites. Check for fleas (tiny dark specks in the fur), ticks (embedded in skin, especially around ears and neck), and ear mites (dark, crumbly discharge in the ears). Over-the-counter flea treatments are available, but consult a vet for the safest options.

When to See a Vet

Seek immediate veterinary care if the cat shows any of the following:

  • Difficulty breathing or persistent coughing
  • Open wounds or active bleeding
  • Severe lethargy (unresponsive to stimulation)
  • Vomiting or diarrhoea lasting more than 24 hours
  • Obvious broken bones or inability to walk

If the cat has a microchip, the vet can scan it and contact the registered owner — often the fastest path to reuniting a found cat.
