Parmesan cheese is a popular dairy product that is enjoyed by many, but is it safe for our feline friends? Cats are obligate carnivores, meaning their bodies are designed to eat meat-based diets. While a small amount of Parmesan cheese is unlikely to be toxic to cats, it is not something they have evolved to eat, and it is high in fat and salt. This means that while it can be a tasty treat for cats, it should only be given infrequently and in small amounts. Harder, aged cheeses like Parmesan are lower in lactose, so they are less likely to upset a cat's stomach, but too much dairy can still cause digestive issues.

What You'll Learn

Parmesan is lower in lactose than other cheeses
Parmesan cheese is not toxic to cats, but it is not ideal to feed it to them. Cats are usually lactose intolerant, and dairy products can upset their digestive system. However, some cats can have a bite of cheese without any issues.
Parmesan cheese is lower in lactose than other cheeses. According to Catherine Rall, a registered dietitian, "As a general rule, the longer a cheese has aged, the less lactose it will have; over time, the lactose in cheese will convert to lactic acid." Parmesan is an aged, hard cheese, and these types of cheeses have less sugar and lactose. Hard cheeses such as cheddar, colby, Swiss, mozzarella, and Monterey Jack are considered "virtually lactose-free."
Soft, fresh, and processed cheeses like cottage cheese, ricotta, and burrata contain significantly more lactose than hard cheeses. However, it's important to note that even within a type of cheese, the lactose content can vary. Biological and enzymatic processes are uneven, and a theoretically "low-lactose" cheese like Parmesan can still have pockets of higher lactose content.
While Parmesan is lower in lactose, it is made from skimmed milk and whey, which is added in. Whey is one of the proteins in dairy that can cause symptoms similar to lactose intolerance in some individuals. Therefore, while Parmesan may be suitable for those with lactose intolerance due to its lower lactose content, the whey may be a factor in triggering symptoms for some people.
In conclusion, Parmesan cheese is generally considered safe for human consumption by those with lactose intolerance due to its lower lactose content. However, the whey in Parmesan may cause similar symptoms to lactose intolerance in some individuals. It is important to note that Parmesan should only be fed to cats in small amounts as a treat due to its high fat content, and it should not be a replacement for their regular diet.

Parmesan is high in fat, salt and calories
Parmesan cheese is not toxic to cats, but it is high in fat, salt, and calories. According to the USDA, a one-ounce serving of Parmesan cheese contains 7.88 grams of fat, 510 mg of sodium, and 119 calories. While a small taste of Parmesan cheese is unlikely to harm your cat, it should not be a regular part of their diet. Cats are obligate carnivores, which means their bodies thrive on a meat-based diet.
The high-fat content of Parmesan cheese can be unhealthy for cats in large quantities. Excessive fat intake can lead to obesity, which can shorten your cat's life and make them more prone to developing diseases such as cancer, diabetes mellitus, and heart disease. Therefore, it is important to monitor your cat's fat intake and ensure they consume Parmesan cheese in moderation.
In addition to the high-fat content, the high salt (sodium) content in Parmesan cheese can also be harmful to cats. Excessive salt intake can make your cat thirsty and potentially harm their kidneys. It is crucial to be mindful of the salt content when feeding Parmesan cheese to your cat and ensure it is only offered as an occasional treat.
Furthermore, Parmesan cheese is calorie-dense, and overconsumption can contribute to weight gain in cats. Obesity is a serious health concern for cats, and maintaining a balanced diet is essential. While an occasional small amount of Parmesan cheese is unlikely to cause harm, it should not replace their regular, species-appropriate diet.
Overall, while Parmesan cheese is not toxic to cats, it is important to remember that it is high in fat, salt, and calories. It should be offered sparingly and only as an occasional treat. As always, monitor your cat's reaction after consuming Parmesan cheese, and if you notice any gastrointestinal upset or other adverse effects, refrain from offering it as a treat in the future.

Parmesan can cause gastrointestinal upset
Parmesan cheese is not toxic to cats, but it can cause gastrointestinal upset. Cats are obligate carnivores, which means their bodies are designed to eat a meat-based diet. While small amounts of Parmesan cheese are generally safe for cats to consume, it is not something they have evolved to eat and should not be a regular part of their diet.
The high-fat content and saltiness of Parmesan cheese can be problematic for cats if consumed in large quantities. Obesity in cats can lead to serious health issues such as cancer, diabetes mellitus, and heart disease. Additionally, the high salt content can make your cat thirsty and potentially harm their kidneys.
Most adult cats are also lactose intolerant, as they lack the digestive enzyme to process dairy effectively. Parmesan cheese is aged and has a low lactose content, but consuming large amounts can still cause digestive issues. Symptoms of gastrointestinal upset in cats include vomiting and diarrhea.
If your cat experiences gastrointestinal upset after consuming Parmesan cheese, it is recommended to withhold food for 12-24 hours. Then, introduce a bland diet of boiled white meat chicken in small amounts several times a day for a couple of days before gradually transitioning back to their normal diet.
In conclusion, while Parmesan cheese is not toxic to cats, it can cause gastrointestinal upset due to its high-fat content, saltiness, and lactose content. It should only be offered as an infrequent treat in small, manageable pieces to avoid choking hazards and potential health complications.

Processed cheese is harmful to cats
While cats can eat small amounts of certain types of cheese, processed cheese is generally harmful to cats and should be avoided.
Processed cheese is often high in salt, which can cause salt toxicity or poisoning in cats. Salt toxicity is a very serious condition that requires veterinary care. In addition, processed cheese often contains harmful additives such as herbs, seasonings, garlic, or onion, which can be toxic to cats.
Processed cheese is also typically high in fat and calories, which can contribute to obesity and other health issues in cats. Cats are naturally attracted to foods high in fat and protein, but it is important to provide them with a healthy and balanced diet that meets their nutritional needs. As obligate carnivores, cats require a diet based mostly on meat to thrive and remain healthy.
Some types of processed cheese, such as cream cheese, are also high in lactose, which can cause digestive issues in cats. Even cats that are not lactose intolerant may experience tummy aches, diarrhoea, or constipation if they consume too much cheese.
Overall, it is best to avoid feeding processed cheese to cats and to offer them natural cheeses like cheddar, parmesan, or goat cheese in moderation if they enjoy cheese as an occasional treat.

Parmesan is not toxic to cats
If your cat eats a large amount of cheese, they may experience an upset stomach, vomiting, and diarrhea. This is because cats are lactose intolerant and most adult cats don't have the digestive enzyme necessary to break down dairy. However, a small taste of Parmesan here and there shouldn't be a problem. In fact, cheese can even be beneficial in moderation as it is high in protein and calcium.
When feeding your cat Parmesan, it's important to avoid any seasonings or additives that could be harmful, such as garlic, onion, or chives. It's also crucial to provide the cheese in small, manageable pieces to prevent choking hazards.
While Parmesan is not toxic, most veterinarians would not suggest feeding it to your cat regularly due to its high-fat content and saltiness. Obesity can shorten your cat's life and make them prone to developing diseases like cancer, diabetes mellitus, and heart disease. Therefore, it's best to offer Parmesan to your cat only as an infrequent treat.
