Getting the right amount of food into your cat is one of the most crucial aspects of keeping them well and content. Too little can result in malnourishment, and too much can lead to obesity and associated medical issues. Lots of cat owners find it hard to know the correct measure, with so many varieties of food and size suggestions out there. Knowing how much to feed your cat is based on age, weight, activity level, and food type.

Consider Your Cat’s Age and Life Stage
Kittens, adult cats, and older cats require different levels of nutrients.
• Kittens (under 1 year): They require extra calories for growth and energy. Feed three to four small meals a day.
•Adult cats (1 to 7 years): The majority of adult cats are satisfied with two balanced meals a day, separated by approximately 8 to 12 hours.
•Senior cats (7+ years): Senior cats might need fewer calories but more quality protein for keeping muscle and supporting joint health.
Weigh your cat regularly, you want to be able to feel their ribs, but not see them too prominently displayed.

Dry Food vs. Wet Food Portions
The food type you provide greatly affects the portion size.
- Things like dry food (kibble): More calories per unit weight, so smaller portions are required. Most adult cats require approximately ¼ to ½ cup of dry food daily, based on brand and calorie density.
- Wet food (canned): Higher moisture content and lower calories per ounce. An average adult cat requires approximately one 3-ounce can per 3 to 3.5 pounds of body weight per day.
Some cat owners utilize a combination of wet and dry food to provide balanced hydration and nutrition.

Review the Feeding Instructions on the Package
Pet food labels provide feeding charts based on weight and age. These are a good starting point, but remember they are general estimates. Adjust based on your cat’s energy level, lifestyle, and metabolism. For example, indoor cats usually need fewer calories than outdoor cats who roam and hunt.

Watch Your Cat’s Weight and Body Condition
Your cat’s body shape is the best indicator of whether you’re feeding the right amount.
Signs your cat is overeating:
• Round abdomen or no waistline
• Afficulty grooming
• Poor activity level
Signs your cat is undernourished:
• Ribs or spine showing
• More meowing than usual or food seeking
• Faded coat or lethargy
Request your vet to conduct a body condition score assessment to maintain your cat at a healthy weight.

Activity Level Matters
Playful cats that climb, play, or venture outdoors burn more calories and require just a bit more food. Indoor or less active cats require smaller portions to avoid weight gain. Interactive toys and regular playtime can also offset energy even if your cat remains indoors.
⸻
Spayed or Neutered Cats
Once spayed or neutered, a cat’s metabolism drops slightly, so they require fewer calories. Reducing your cat’s portion size by around 10 percent will prevent them from gaining weight.
⸻
Treats and Extras Count Too
Treats should constitute no more than 10 percent of your cat’s daily calories. Overfeeding your cat on treats can result in obesity and nutritional unbalance. Use low-calorie, vet-recommended treats and only give them out on an occasional basis.

When to Consult Your Vet
If you’re unsure about your cat’s ideal weight or diet plan, your vet can create a customized feeding guide. This is especially important if your cat has special dietary needs, health conditions, or food sensitivities.
