How to Can Homemade Cat Food

This guide teaches you how to can homemade cat food safely and effectively using proven methods. You’ll learn essential equipment, balanced recipes, and proper storage to provide your cat with nutritious, preservative-free meals.

Key Takeaways

• Safety First: Always use a pressure canner—not a water bath—to eliminate harmful bacteria like Clostridium botulinum, which can thrive in low-acid foods like meat.
• Balanced Nutrition is Crucial: Homemade cat food must include taurine, arachidonic acid, and vitamin A, as cats cannot synthesize these nutrients on their own.
• Use High-Quality Ingredients: Choose fresh, human-grade meats (chicken, turkey, rabbit) and avoid onions, garlic, chocolate, and grapes, which are toxic to cats.
• Follow Tested Recipes: Never improvise. Use vet-approved or scientifically formulated recipes to ensure your cat gets complete nutrition.
• Proper Equipment Matters: Invest in a quality pressure canner, jars, lids, and a food processor or grinder for consistent results.
• Label and Rotate Stock: Clearly label each jar with the date and contents, and use older cans first to maintain freshness and safety.
• Consult Your Veterinarian: Before switching your cat to a homemade diet, discuss it with your vet to ensure it meets your pet’s health needs.

How to Can Homemade Cat Food: A Complete Step-by-Step Guide

If you’re a cat parent who wants more control over what your furry friend eats, learning how to can homemade cat food is a smart and rewarding choice. Commercial cat foods often contain fillers, preservatives, and by-products that may not support optimal health. By preparing and canning your own meals, you can offer your cat fresh, wholesome, nutrient-rich food—without the mystery ingredients.

But here’s the catch: cats have very specific dietary needs. Unlike dogs, they’re obligate carnivores, meaning they require animal-based proteins and certain nutrients that only come from meat. Simply cooking up some chicken and calling it a day won’t cut it. And when it comes to preserving that food through canning, safety is non-negotiable.

In this guide, you’ll learn everything you need to know about how to can homemade cat food—from choosing the right ingredients and equipment to following safe canning procedures and storing your finished jars. Whether you’re feeding one cat or a whole clowder, this method lets you batch-prepare meals that last for months, saving time and giving you peace of mind.

By the end of this guide, you’ll be able to confidently prepare, can, and serve nutritious, delicious meals your cat will love—and your vet will approve of.

Why Can Homemade Cat Food?

Canning homemade cat food offers several benefits over raw feeding or daily cooking:

• Convenience: Once canned, meals are ready to serve—just open, warm, and feed. No daily prep required.
• Long Shelf Life: Properly canned food lasts 1–2 years in the pantry, making it ideal for busy pet parents.
• Reduced Risk of Contamination: Unlike raw diets, canned food is heated to temperatures that kill bacteria, parasites, and pathogens.
• Consistent Nutrition: You control the ingredients, ensuring every meal is balanced and free from allergens or fillers.
• Cost-Effective Over Time: Buying meat in bulk and canning it yourself can be cheaper than premium commercial wet food.

However, it’s important to note that canning is not the same as freezing or dehydrating. It requires precise techniques to ensure safety and nutritional integrity.

Essential Equipment for Canning Cat Food

Before you start, gather the right tools. Using the correct equipment ensures safe, effective canning and prevents spoilage or foodborne illness.

Pressure Canner

This is the most important piece of equipment. Never use a water bath canner for meat-based foods. Cats eat low-acid foods (like poultry, beef, or fish), and only a pressure canner reaches the high temperatures (240°F/116°C) needed to destroy Clostridium botulinum spores.

Look for a dial-gauge or weighted-gauge pressure canner with a capacity of at least 16–23 quarts. Popular brands include Presto, All-American, and Mirro.

Canning Jars

Use standard Mason jars—either pint (16 oz) or half-pint (8 oz) sizes. Pint jars are ideal for adult cats, while half-pints work well for kittens or smaller portions.

Choose jars with two-piece lids: a flat lid with a sealing compound and a screw band to hold it in place. Always inspect jars for cracks, chips, or defects before use.

Lids and Bands

Use new lids every time. The sealing compound only works once. Reusing lids can lead to failed seals and spoiled food. Screw bands can be reused if they’re rust-free and undamaged.

Jar Lifter and Canning Funnel

A jar lifter safely removes hot jars from the canner. A wide-mouth canning funnel prevents spills when filling jars.

Food Processor or Meat Grinder

Cats can’t chew large chunks, so you’ll need to grind or puree the meat mixture to a smooth, uniform texture. A food processor works well for small batches; a meat grinder is better for larger quantities.

Kitchen Scale

Accurate measurements are crucial for balanced nutrition. Use a digital kitchen scale to weigh ingredients precisely.

Timer and Thermometer

A timer ensures proper processing times. A thermometer helps verify water and food temperatures during prep.

Choosing the Right Ingredients

Not all meats and supplements are created equal. To make safe, nutritious cat food, you need high-quality, species-appropriate ingredients.

Protein Sources

Use fresh, human-grade meats. Avoid processed or seasoned meats. Good options include:

• Chicken (with bones ground or removed)
• Turkey (light and dark meat)
• Rabbit
• Duck
• Beef heart (a rich source of taurine)
• Organ meats (liver, kidney)—use in moderation (no more than 10% of total weight)

Avoid pork (risk of parasites) and raw fish (contains thiaminase, which destroys vitamin B1).

Supplements (Non-Negotiable)

Cats need specific nutrients that must be added manually:

• Taurine: Essential for heart and eye health. Add 250–500 mg per pound of meat.
• Vitamin E: Acts as a natural preservative and supports immune function. Use 10–20 IU per pound of meat.
• Fish Oil (Omega-3s): Supports skin, coat, and joint health. Use 100–200 mg EPA/DHA per pound of meat.
• Calcium: If using boneless meat, add 800–1000 mg calcium per pound (use calcium carbonate or crushed eggshells).
• Arachidonic Acid: Found in animal fats; ensure fat content is adequate or supplement if needed.

What to Avoid

Never include:

• Onions, garlic, chives (toxic to cats)
• Chocolate, caffeine, alcohol
• Grapes and raisins
• Xylitol (artificial sweetener)
• Excessive salt or sugar
• Dairy (many cats are lactose intolerant)

Step-by-Step Guide to Canning Homemade Cat Food

Now that you have your equipment and ingredients, let’s walk through the canning process.

Step 1: Prepare Your Workspace

Clean and sanitize all surfaces, tools, and equipment. Wash your hands thoroughly. Set up your canning station with jars, lids, funnel, lifter, and timer within reach.

Step 2: Prepare the Meat Mixture

Use a tested recipe. Here’s a simple, vet-approved example:

Basic Chicken & Liver Recipe (for 10 lbs of meat):

• 8 lbs boneless chicken thighs (or a mix of thigh and breast)
• 1 lb chicken liver
• 1 lb beef heart (optional, for extra taurine)
• 1 cup water or low-sodium broth
• 500 mg taurine powder
• 1000 mg calcium carbonate (if using boneless meat)
• 20 IU vitamin E
• 200 mg fish oil

Step 3: Cook the Meat (Optional but Recommended)

While some raw canning methods exist, lightly cooking the meat before canning improves texture and ensures even heat distribution. It also makes grinding easier.

• Boil or bake the meat until fully cooked (internal temp of 165°F/74°C).
• Let it cool slightly, then remove any large pieces of fat or gristle.
• Grind or process the meat into a fine paste using a food processor or meat grinder.
• Add supplements and liquid, then blend until smooth.

Step 4: Sterilize Jars and Prepare Lids

• Wash jars in hot, soapy water and rinse well.
• Place jars in your pressure canner and fill with water up to the jar shoulders. Heat to simmer (180°F/82°C) while you prepare the food.
• Place lids in a small saucepan and heat in simmering water (not boiling) for 10 minutes to soften the sealing compound.
• Keep lids warm until ready to use.

Step 5: Fill the Jars

• Use a canning funnel to fill jars with the meat mixture.
• Leave 1 inch of headspace (the space between the food and the lid).
• Remove air bubbles by gently tapping the jar or using a non-metallic spatula.
• Wipe the jar rims with a clean, damp cloth to ensure a good seal.
• Place a warm lid on each jar and screw on the band fingertip-tight (don’t over-tighten).

Step 6: Process in the Pressure Canner

• Place filled jars in the pressure canner using the jar rack.
• Lock the lid and heat on high until steam flows steadily from the vent.
• Vent the canner for 10 minutes to remove air, then close the vent and build pressure.
• Process pints for 75 minutes and quarts for 90 minutes at 10 psi (adjust for altitude if needed—see troubleshooting).
• After processing, turn off the heat and let the canner depressurize naturally. Do not force-cool.

Step 7: Cool and Store

• Once pressure returns to zero, wait 10 minutes, then carefully open the lid away from your face.
• Use a jar lifter to remove jars and place them on a towel or cooling rack.
• Let jars cool for 12–24 hours. You’ll hear a “ping” as lids seal.
• Check seals: press the center of each lid. If it doesn’t flex, it’s sealed. If it pops, refrigerate and use within a few days.
• Remove screw bands, wipe jars clean, and label with the date and contents.
• Store in a cool, dark place (pantry or cupboard). Properly sealed jars last 1–2 years.

Serving Canned Homemade Cat Food

When it’s mealtime, simply:

• Open a jar and scoop out the desired amount.
• Warm slightly in a bowl of warm water (never microwave directly in the jar).
• Serve at room temperature or slightly warm—cats prefer it that way.
• Refrigerate leftovers and use within 3–4 days.

Most cats transition easily to canned homemade food. If your cat is picky, mix a small amount with their current food and gradually increase the ratio over 7–10 days.

Troubleshooting Common Issues

Even with careful preparation, problems can arise. Here’s how to handle them:

Jars Didn’t Seal

• Cause: Improper headspace, dirty rims, old lids, or insufficient processing time.
• Solution: Refrigerate unsealed jars and use within a few days. Re-can only if the food is still cold and hasn’t spoiled.

Food Spoiled After Opening

• Cause: Contamination during filling or under-processing.
• Solution: Discard immediately. Check your process—ensure full processing time and clean technique.

Cloudy or Separated Food

• Cause: Normal for high-moisture, high-protein foods. Fat and liquid may separate during storage.
• Solution: Stir gently before serving. It’s safe and nutritious.

Altitude Adjustments

If you live above 1,000 feet, increase pressure:

• 1,000–2,000 ft: 11 psi
• 2,000–4,000 ft: 12 psi
• 4,000–6,000 ft: 13 psi
• 6,000–8,000 ft: 14 psi
• Above 8,000 ft: 15 psi

Always consult your canner’s manual for specific instructions.

Safety Tips and Best Practices

• Never skip the pressure canner. Botulism is deadly and invisible.
• Use only tested recipes. Don’t experiment with ratios or ingredients.
• Keep everything clean. Sanitize surfaces, tools, and hands.
• Don’t overfill jars. Leave proper headspace for expansion.
• Label everything. Include date, recipe, and any supplements used.
• Rotate your stock. Use older jars first (FIFO: First In, First Out).
• Monitor your cat’s health. Watch for changes in energy, coat, digestion, or weight.
