Most diabetic cats need insulin on a fixed daily schedule, and meals must match the vet's protocol, since arbitrary meal shifts can cause hypoglycemia.

Protocols usually anchor meals to injection times; whether food comes before or with the shot depends on insulin type and glucose curves, and the vet decides.

High-protein, low-carbohydrate diets are commonly used in feline diabetes, with wet foods generally lower in carbs, but diet changes require monitored dose adjustments.

Recognize hypoglycemia at home: sudden weakness, wobbling, or seizures mean call the vet immediately; dose changes are always driven by monitoring data.
