Portion and Timing Guide

Indoor cats burn fewer calories than outdoor cats. Overfeeding is one of the most common issues in apartment cats and leads directly to joint, heart, and diabetes risks.

A simple scheduled feeding approach prevents overeating and gives you a clear picture of your cat's appetite, which is one of the first signs of illness.

  • Feed twice daily at fixed times
  • Follow package guidelines as a starting point, then adjust
  • Weigh portions with a kitchen scale for accuracy
  • Always provide fresh water in a separate bowl from food
  • Consider a water fountain to encourage drinking
  • Remove uneaten wet food after 30 minutes

Common Feeding Mistakes

Small habits that make a big difference over time.

Free-feeding dry food

Leaving a full bowl out all day makes it hard to track how much your cat is eating. Scheduled meals give you better visibility into appetite changes.

Ignoring water intake

Cats have a low thirst drive. If your cat eats mostly dry food, it may be chronically under-hydrated without obvious signs.

Switching food too fast

A sudden change in diet often causes digestive upset. Transition over 7-10 days by gradually mixing the new food with the old.

Feeding human food as treats

Many common foods are toxic to cats, including onion, garlic, grapes, and chocolate. Stick to cat-specific treats and use them sparingly.
