Raw meat carries real risks for cats, including bacterial contamination, parasitic infection, and nutritional imbalances. Both the CDC and the American Veterinary Medical Association recommend against feeding raw diets to cats and dogs. While cats are obligate carnivores built to process animal protein, that doesn’t mean raw meat from a grocery store or commercial raw pet food is automatically safe.
Bacterial Contamination Is Common
The most immediate concern with raw meat diets is foodborne bacteria. A study published in The Veterinary Record tested 35 commercial frozen raw pet foods across eight brands and found Salmonella in 20% of samples, Listeria monocytogenes in 54%, and the dangerous E. coli strain O157:H7 in 23%. The cats eating these contaminated products often showed no symptoms at all, meaning they became silent carriers shedding harmful bacteria in their feces, saliva, and around the house.
This is where raw feeding becomes a household problem, not just a pet problem. Bacteria from raw pet food spread through food bowls, countertops, litter boxes, and face licking. The CDC specifically warns that raw pet food “can also make you and your family sick when these germs spread around your kitchen and home.” Young children, elderly family members, pregnant women, and anyone with a weakened immune system face the greatest risk.
Parasites in Raw Meat
Raw meat can harbor parasites that cooking would destroy. Toxoplasma gondii is the best-known example. Cats are the parasite’s primary host and become infected by eating raw or undercooked meat from infected animals. Once infected, a cat sheds the parasite in its feces for several weeks, creating a transmission risk for everyone in the household. Toxoplasmosis is particularly dangerous during pregnancy, where it can cause serious birth defects.
Some people assume freezing meat kills parasites before feeding. The USDA notes that sub-zero freezing can destroy certain parasites like Trichina, but only under “very strict government-supervised conditions.” Home freezing is not reliable enough to eliminate parasites from meat. Cooking remains the only sure method.
Freezing and Dehydrating Don’t Solve the Problem
A common selling point for commercial raw cat food is that it’s been frozen, freeze-dried, or dehydrated. The CDC is clear on this: these processes “only reduce the amount of germs. These processes do not kill all germs that might be on the food.” Even newer techniques like high-pressure processing and irradiation, which some premium brands use, don’t yet have enough data behind them for the CDC to consider those products safe. They’re still classified as raw pet food with the same warnings attached.
Nutritional Imbalances Are Easy to Get Wrong
Feeding a cat plain raw meat, even high-quality cuts, doesn’t provide a complete diet. Muscle meat alone is very high in phosphorus and low in calcium. Cats need a calcium-to-phosphorus ratio between 1:1 and 2:1. When that ratio is off for extended periods, excess phosphorus pulls calcium from the bones, potentially leading to a condition called osteodystrophy. In severe cases this causes pathological fractures and a softening of the jaw sometimes called “rubber jaw.”
Formulating a balanced raw diet requires adding bone meal or ground bone, organ meats in specific proportions, taurine supplements, and other vitamins and minerals. Getting it right is possible but demands precision. Many homemade raw diets analyzed by veterinary nutritionists turn out to be deficient in one or more essential nutrients.
The Digestibility Argument
Proponents of raw feeding often point to better protein digestibility as a key advantage. There is some evidence here: a few studies have shown that cats digest protein from raw meat slightly better than from dry kibble. But the reason may not be what raw feeding advocates assume. When researchers cooked the same raw meat before feeding it, the digestibility stayed the same. That suggests the advantage isn’t about raw enzymes or “living food.” It’s more likely that the heavy processing involved in making kibble (extrusion at high temperatures) reduces protein quality. A gently cooked homemade diet could offer the same digestibility benefit without the bacterial risk.
What About Dental Health?
Another common claim is that raw meat and raw bones clean a cat’s teeth naturally, reducing plaque and tartar buildup. The evidence for this is thin. Feral cats on Marion Island off South Africa, eating a fully natural diet of mostly birds, still showed periodontal disease in 61% of individuals. A wild diet didn’t protect them. Only 9% had visible tartar, suggesting that chewing raw prey may reduce calculus somewhat, but it clearly doesn’t prevent gum disease.
Raw Bones vs. Cooked Bones
If you do feed raw meat, one legitimate distinction is between raw and cooked bones. Cooked bones, especially chicken bones, become brittle and splinter into sharp fragments that can puncture your cat’s mouth, throat, stomach, or intestines. They can also cause blockages. Raw bones are softer and less likely to splinter, though they still carry some risk of causing digestive injuries or breaking teeth. Neither type is completely without hazard, but cooked bones are significantly more dangerous.
Reducing Risk if You Still Choose Raw
Some cat owners decide the perceived benefits are worth the risks. If you go this route, a few practices can reduce (but not eliminate) the danger:
- Use commercial raw diets formulated to AAFCO standards rather than winging it with grocery store meat. These are at least designed to be nutritionally complete, even if contamination risk remains.
- Handle raw pet food like you’d handle raw chicken for yourself. Wash bowls, surfaces, and your hands with hot soapy water after every feeding. Don’t let raw food sit at room temperature.
- Keep raw-fed cats away from immunocompromised household members as much as possible, especially their litter boxes.
- Consider lightly cooking the meat instead. Since the digestibility advantage appears to survive gentle cooking, you can get many of the same nutritional benefits while killing most pathogens. You’d still need to add supplements to make the diet complete.
The bottom line is straightforward. Raw meat poses documented risks from bacteria, parasites, and nutritional imbalance, and the supposed benefits either lack strong evidence or can be achieved through safer alternatives. Major health organizations recommend against it for both pet and human safety.
