What to consider for Raw Cat Food For Cats Over 15 Lbs

Cats over 15 lbs often have lower energy needs per pound than smaller cats, so calorie density matters. Raw diets are naturally high in protein and moisture, which can help with weight management and urinary health. However, larger cats may need careful portion control to avoid overfeeding. Also, ensure the food is complete and balanced for adult maintenance, and consider your cat’s activity level and any health conditions like arthritis or kidney disease. Always transition slowly to a raw diet.

What to look for in a cat food

Look for an AAFCO statement indicating the food is complete and balanced for adult maintenance. The first ingredient should be a named meat (e.g., chicken, beef) to ensure high animal protein. Taurine must be present, as cats cannot synthesize it. Moisture content is important; raw foods typically have high moisture, supporting urinary health. For larger cats, moderate fat content helps control calories. Also consider life-stage suitability; avoid all-life-stages foods for seniors without checking specific nutrient levels.

How we chose these picks

  • Evaluated protein and fat content to match needs of larger cats.
  • Checked for named meat as first ingredient and absence of artificial additives.
  • Reviewed AAFCO nutritional adequacy statements.
  • Considered brand reputation and ingredient sourcing.
  • Read customer feedback on palatability and digestibility.
  • Compared price per pound to ensure value.
  • Ensured products are widely available for purchase.
  • Never ranked a product higher just because it pays a commission.

What to avoid

  • Avoid foods with unnamed meat or by-products as first ingredient.
  • Steer clear of recipes with insufficient animal protein (less than 30% dry matter).
  • Do not choose a food that lacks taurine supplementation.
  • Be cautious with all-life-stages formulas for seniors; they may have excess phosphorus.
  • Avoid abrupt diet changes; transition over 7 to 10 days.

This freeze-dried raw food features real chicken as the first ingredient, providing high animal protein for muscle maintenance. It's grain-free and includes probiotics for digestive health. The raw bites are easy to portion for larger cats. One limitation is the higher price per pound compared to kibble, but the quality justifies the cost.

This limited-ingredient diet uses chicken and salmon as protein sources, with no grains or artificial additives. It's fortified with organic vegetables and probiotics to aid digestion.

Tiki Cat's freeze-dried raw offers a high-moisture, high-protein option that mimics a wet food texture when rehydrated. It's made with whole prey ingredients and no fillers. This helps with hydration for larger cats. A downside is the need to rehydrate before serving, which adds prep time.

Blue Buffalo Wilderness Raw Bites Grain-Free Cat Food, Chicken

View on Amazon

This budget-friendly option still delivers real chicken as the first ingredient and freeze-dried raw pieces mixed with kibble. It provides a balance of raw nutrition and convenience.

Before You Buy

Key Buying Factors

01

Calorie Density

Larger cats often need fewer calories per pound. Look for foods with moderate calorie content to prevent weight gain. Raw diets vary; check the kcal per cup or ounce.

02

Protein Source

A named meat (chicken, beef, fish) should be first. Novel proteins like rabbit or venison can help with allergies. Ensure the protein level is high enough for muscle maintenance.

03

Fat Content

Fat provides energy but excess can lead to obesity. For cats over 15 lbs, aim for 10-15% fat on a dry matter basis. Lower fat may be needed for weight loss.

04

Moisture Level

Raw food naturally has high moisture (70-80%), which supports kidney and urinary health. This is beneficial for larger cats prone to dehydration.

05

AAFCO Statement

Ensure the food is complete and balanced for adult maintenance. Avoid treats or supplements that are not nutritionally adequate as a sole diet.

Living With It

Care, Cost and Maintenance

Portion Control

Feed according to your cat's ideal weight, not current weight. Use a kitchen scale for accuracy. Raw food can be calorie-dense; adjust portions if your cat is gaining or losing weight.

Transitioning to Raw

Gradually mix raw food with current food over 7 to 10 days. Start with 25% raw, 75% old food, then increase. Monitor stool consistency and appetite. Consult your vet before switching.

Handling and Storage

Thaw frozen raw in the refrigerator, not on the counter. Use within 2 days after thawing. Freeze-dried raw should be stored in a cool, dry place. Wash hands and bowls thoroughly after handling raw meat.

Pro tip

Use a digital kitchen scale to portion raw food accurately; eyeballing can lead to overfeeding, especially with calorie-dense freeze-dried raw.

Frequently asked questions

How much raw cat food should I feed my 15 lb cat?
Feeding amounts vary by brand and calorie density. As a general guideline, an adult cat needs about 20 to 30 calories per pound of ideal body weight per day. For a 15 lb cat, that's 300 to 450 calories. Check the product's feeding guide; most raw foods recommend 1 to 2 patties or 1/4 to 1/2 cup per day. Adjust based on activity level and weight goals. Always consult your veterinarian for personalized advice.
Is raw cat food better than dry kibble for large cats?
Raw food has higher moisture content, which can support urinary health and hydration, important for large cats prone to kidney issues. It also typically has more animal protein and fewer carbohydrates, which may help with weight management. However, raw diets require careful handling to avoid bacterial contamination and must be nutritionally complete. Dry kibble is convenient and shelf-stable. The best choice depends on your cat's health needs and your lifestyle. Discuss with your vet.
Can grain-free raw cat food cause taurine deficiency?
Grain-free diets do not inherently cause taurine deficiency. Taurine is an essential amino acid for cats, and reputable raw food brands supplement it to meet AAFCO standards. However, some grain-free diets may use ingredients that interfere with taurine absorption, such as certain legumes. Always check the guaranteed analysis for taurine content (minimum 0.1% on a dry matter basis for adult cats). Choose brands with a history of safe formulation.
Is raw cat food appropriate for kittens?
Kittens have higher nutritional needs for growth, including more protein, fat, calcium, and phosphorus. Some raw foods are formulated for all life stages, but you should ensure the product is specifically labeled for growth or all life stages. Kittens also have developing immune systems, so raw food carries a higher risk of bacterial infection. Consult your veterinarian before feeding raw to kittens. Many experts recommend waiting until adulthood.
What should I feed a senior cat over 15 lbs?
Senior cats often need fewer calories, more easily digestible protein, and joint support. Look for raw foods with moderate fat (10-15%) and added glucosamine or omega-3s. Ensure the food is complete for adult maintenance; some senior formulas have reduced phosphorus for kidney health. Always consult your vet, as seniors may have underlying conditions like kidney disease or hyperthyroidism that require a specific diet.
Can raw cat food help with urinary health?
Raw food's high moisture content (70-80%) helps dilute urine and reduce the risk of urinary crystals and stones. However, the mineral balance (magnesium, phosphorus, calcium) is also crucial. Some raw diets are formulated to maintain a healthy urinary pH. If your cat has a history of urinary issues, choose a diet specifically designed for urinary health and consult your veterinarian. Raw food is not a cure-all.
How can I help my overweight cat lose weight on a raw diet?
First, calculate your cat's ideal weight and feed for that weight, not the current weight. Choose a raw food with lower fat content (under 10% dry matter) and higher protein to preserve muscle. Measure portions precisely using a scale. Increase exercise with interactive toys. Avoid free-feeding. Monitor weight weekly and adjust portions as needed. Always consult your vet before starting a weight loss plan.
My cat is a picky eater; will raw food be accepted?
Many cats are attracted to the smell and taste of raw food. Start with a single protein like chicken or fish. Mix a small amount of raw with their current food and gradually increase. Some freeze-dried raw foods can be crumbled as a topper. Patience is key; it may take several attempts. If your cat refuses, try a different protein or brand. Never starve your cat; ensure they eat something.
Is it safe to feed raw cat food to a cat with kidney disease?
Cats with kidney disease require controlled phosphorus and protein levels. Raw diets are often high in protein, which may not be suitable for advanced kidney disease. However, some raw foods are formulated with lower phosphorus. Always consult your veterinarian before feeding raw to a cat with kidney disease. They may recommend a therapeutic diet or specific raw brand that meets your cat's needs.
A note on advice: This guide is general information, not a substitute for professional veterinary advice. Talk to your vet before changing your dog's diet or care routine, especially if your dog has allergies, kidney disease, pancreatitis, obesity, heart disease or any other medical condition.
