Severely emaciated or dehydrated mammals should not be fed solid food right away. Should solid food be fed immediately?

• A. True
• B. False
• C. Only after IV fluids
• D. Only with soft foods

Answer: (A)

When a mammal is severely emaciated or dehydrated, the priority is to stabilize hydration and electrolyte balance before introducing solid food. Feeding solids right away can overwhelm a stressed gut, increase the risk of aspiration, and trigger refeeding syndrome, where a surge of insulin drives important minerals like phosphorus, potassium, and magnesium into cells. This can lead to dangerous drops in these electrolytes and compromise heart and organ function.

So the best approach is to start with fluids to restore hydration (and address electrolytes), using the level of care appropriate for the severity—oral fluids for milder cases or medical fluids (often IV) for more severe dehydration. Once the animal is rehydrated and tolerating fluids, you can begin with easily digestible, soft or liquid foods in small amounts, gradually increasing as the animal improves. This gradual reintroduction helps the gut adapt and reduces complications.

In short, solid food should not be fed immediately; stabilization with fluids comes first, followed by careful, gradual refeeding.
