Frequently Asked Questions

How much should I feed my cat per day?
A typical 10-lb adult indoor cat needs about 200-250 calories per day, which translates to roughly 1/2 to 2/3 cup of dry food or about 1.5 cans of wet food (5.5 oz cans). Kittens need more calories per pound due to growth.
Should I free-feed my cat?
Free-feeding (leaving dry food out all day) works for some cats who self-regulate, but many cats will overeat. Measured meals 2 times per day are recommended to prevent obesity. Kittens under 6 months may benefit from free-feeding.
Is wet or dry food better for cats?
Wet food provides better hydration (important for urinary tract health) and is typically higher in protein and lower in carbohydrates. Dry food is convenient and economical. Many vets recommend a combination for optimal nutrition and hydration.
