Expert Tips for Cornish Rexs
Feed 2–3 meals daily. May need 10-15% more calories than similarly sized cats due to thin coat. Keep warm during and after meals in cool environments.
Practical Feeding Guidelines
Meal Frequency
Feed 2-3 small meals per day. Cats are natural grazers, but measured portions prevent overeating.
Wet vs Dry Food
A mix of wet and dry food is ideal. Wet food provides hydration while dry food supports dental health.
Hydration
Cats need about 3.5–4.5 oz of water per 5 lbs of body weight daily. A water fountain can encourage drinking.
Weight Monitoring
Weigh your Cornish Rex monthly. Indoor cats are especially prone to weight gain — adjust portions if needed.
