FAQs
How many cans of wet food should I feed my cat per day?
A 10 lb adult cat typically needs 2–3 standard 3 oz cans per day if eating wet food exclusively. Adjust based on the calorie content printed on your specific brand.
Can I feed my cat wet food twice a day?
Yes — twice daily is the most common feeding schedule. Split the total daily portion in half, serve morning and evening, and discard any uneaten food after 30–60 minutes to prevent spoilage.
Is it OK to leave wet food out all day?
No. Wet food spoils within 1–4 hours at room temperature. Always serve fresh portions and refrigerate any opened cans. Unlike dry food, wet food should never be left out for free feeding.
