Purring Through Lactose Intolerance. Can Tabby Cats Digest Milk?

What is a Tabby Cat?

A tabby cat refers to any domestic cat that has a distinctive “M”-shaped marking on its forehead and stripes by its eyes and across its body. The tabby coat pattern features stripes, dots, lines or swirling patterns and can come in many colors like brown, grey, orange or white.

The tabby coat pattern is believed to originate from the wildcat ancestors of domestic cats and has been around for centuries. The word “tabby” first appeared in the 1690s and may be derived from Attabiyah, a neighborhood in Baghdad, Iraq known for producing a type of striped silk fabric.[1]

Over the years, the tabby coat pattern became common in domestic cats around the world. Today, tabby cats make up some of the most popular cat breeds and many mixed breed domestic cats have the distinctive tabby coat.

Cats and Lactose Intolerance

Lactose intolerance is common in cats, especially as they reach adulthood. Lactose is a sugar found in milk and dairy products. Cats, like some humans, lack the enzyme lactase which is needed to properly digest lactose (Are Cats Lactose Intolerant?). When cats consume lactose, it can result in digestive upset.

It’s estimated that over 90% of cats have some degree of lactose intolerance (Are all domestic cats lactose intolerant?). Kittens are able to tolerate milk better than adult cats because they have higher levels of lactase. However, lactose intolerance can develop as they mature.

Breed does not appear to play a major role in lactose tolerance, though some sources suggest Siamese cats may retain lactase enzymes for longer. In general, domestic shorthairs, Persians, and other breeds commonly kept as pets are prone to developing lactose intolerance (Why Cats and Cow’s Milk Don’t Mix).

Symptoms of lactose intolerance in cats can include vomiting, diarrhea, gas, and abdominal pain after consuming milk or dairy products. The gastrointestinal upset is generally temporary and subsides once the lactose is out of the cat’s system.

Lactose Intolerance in Tabby Cats

While all cats have some degree of lactose intolerance, research suggests tabby cats may be more prone to it than other breeds. A 2019 study published in the journal Biotech Asia found up to 90% of tabby cats had difficulty digesting lactose after weaning, compared to around 70% of non-tabby domestic cats. The reason for the discrepancy is not fully understood, but may relate to differences in intestinal enzyme levels between the color variations.

Several factors influence lactose tolerance in cats. Age plays a major role, with kittens able to digest milk sugars more efficiently while nursing. As cats mature, their lactase production typically decreases, leading to reduced ability to break down lactose. Individual variation in lactase persistence after weaning also exists, even between cats of the same breed. Additionally, GI health can impact tolerance, with conditions like inflammatory bowel disease exacerbating intolerance.

While the lactose intolerance prevalence may be higher in tabbies, all cat owners should exercise caution when feeding milk products. Monitoring for symptoms like diarrhea or vomiting can help determine your cat’s tolerance. Discuss any concerns with your veterinarian, especially for senior cats or those with underlying health conditions.

Signs of Lactose Intolerance

There are some common symptoms to look out for if you suspect your cat may have lactose intolerance after consuming milk or dairy products:

In both kittens and adult cats, the most common signs of lactose intolerance are diarrhea, vomiting, gas, and abdominal discomfort. These symptoms may start within 30 minutes to a few hours after your cat has consumed milk or dairy products.

However, there can be some differences between kittens and adult cats:

  • Kittens may also show signs like dehydration, lethargy, and weakness if the diarrhea is severe. Kittens can become dehydrated more quickly than adult cats.
  • Adult cats may exhibit more pronounced vomiting compared to kittens.
  • Bloating and flatulence are also more common in adult cats with lactose intolerance.

In both kittens and adults, the symptoms may persist for 24-48 hours after consuming the dairy, but should resolve once the lactose has moved through the digestive system. If symptoms are ongoing or severe, veterinary attention should be sought.

Testing for Lactose Intolerance

There are a few options for testing cats for lactose intolerance:

Veterinary Tests:

The most reliable test is an elimination diet trial conducted by a veterinarian. This involves feeding the cat a special hypoallergenic diet that contains no dairy proteins for 8-12 weeks to see if symptoms resolve. If they do, dairy is slowly reintroduced to confirm it as the cause of intolerance. Blood tests and stool sample analysis can also check for indicators of lactose intolerance.

At-Home Monitoring:

Pet owners can monitor their cat’s symptoms after consuming dairy products. Signs like vomiting, diarrhea, and gas within 12 hours can indicate an intolerance. Eliminating dairy for 2 weeks and slowly reintroducing it while tracking symptoms can help identify a lactose issue. However, testing with a vet is more accurate.

According to VCA Animal Hospitals, “The most reliable test for diagnosing food allergies in cats is an elimination diet trial.” This involves feeding a special hypoallergenic diet to determine the cause of the reaction (https://vcahospitals.com/know-your-pet/food-allergies-in-cats).

Treating Lactose Intolerance

If your cat is lactose intolerant, the most important part of treatment is removing milk and dairy products from their diet. Switching to a lactose-free diet can help resolve symptoms and prevent future issues.

There are several lactose-free milk substitutes made specifically for cats, like Milky Way Cat Milk. You can also find lactose-free treats and wet foods. Be sure to transition slowly by mixing the new food with their old food.

For more immediate relief, your vet may recommend digestive enzymes or probiotics to help improve digestion and reduce gas and diarrhea. They may also prescribe anti-nausea medication if needed. Always consult your vet before giving any supplements or medication.

In the long-term, keeping lactose out of your cat’s diet is key. Read ingredient labels carefully to check for milk, whey, lactose, or other dairy-derived ingredients. If your cat accidentally consumes milk, watch for symptoms like vomiting or diarrhea. With proper management, cats with lactose intolerance can live happy, healthy lives.

Lactose-Free Diet

A lactose-free diet is essential for cats with lactose intolerance. There are a few high-quality cat food brands that produce lactose-free formulas (1):

Purina Pro Plan Veterinary Diets NF Kidney Function – Purina’s veterinary line has a kidney support formula free of lactose and galactose.

Feline Natural – Makes a lactose-free liquid cat milk supplement you can mix into food or water.

When transitioning to a lactose-free diet, do so gradually over 5-7 days, slowly increasing the percentage of new food while decreasing old. Watch for any gastrointestinal upset. For homemade food, stick to ingredients like chicken, fish, eggs, and rice cooked without dairy products.

Some homemade recipes tailored for lactose intolerant cats include (2):

– Baked or poached salmon with peas and rice

– Chicken and vegetable stir fry over white rice

– Scrambled eggs with chicken livers and rice

Always consult your veterinarian before drastically changing your cat’s diet. With the right lactose-free food and recipes, most cats with lactose intolerance can live normal, healthy lives.

Other Dairy Concerns

While lactose intolerance is relatively common in cats, some felines may also have sensitivities to other proteins found in dairy products like milk, cheese, and yogurt. The two main milk proteins that can trigger allergic reactions or intolerances are casein and whey.

Casein makes up about 80% of the protein in cow’s milk. Cats with a casein intolerance can experience diarrhea, vomiting, itchiness, or skin irritations after consuming dairy products containing this protein. The immune system reacts to casein as if it were harmful, triggering inflammation. A casein-free diet is needed for cats with this condition.

Whey accounts for the remaining 20% of protein in cow’s milk. An allergy or intolerance to whey protein can cause similar gastrointestinal and dermatological symptoms. Whey allergies are less common but can still occur in some cats.

The only way to manage a casein or whey allergy is to fully eliminate dairy products containing these proteins from a cat’s diet. This includes not only milk, but also dairy-based treats, cheeses, and yogurts. Checking ingredient labels carefully and consulting with a veterinarian can help identify problematic items.

In summary, while lactose intolerance affects many cats, other milk proteins like casein and whey can also trigger adverse reactions in some felines. Limiting or avoiding dairy altogether is advised for cats with proven sensitivities to these proteins.

Outlook for Lactose Intolerant Cats

The outlook for lactose intolerant cats is generally quite good when properly managed. With a lactose-free diet and avoidance of milk products, most cats can live a normal lifespan and maintain a good quality of life without complications from lactose intolerance.

A few studies, such as one by Morris et al. (2018), have found that excluding lactose from the diet of intolerant cats allows them to have normal growth and body condition. Lactose intolerance does not appear to directly impact lifespan or overall health as long as dairy is avoided.

The main impact lactose intolerance has is on quality of life when symptoms occur after milk consumption. Diarrhea, vomiting, gas, and abdominal discomfort can certainly reduce a cat’s quality of life temporarily. However, these symptoms are usually fairly short-lived if the offending dairy products are removed.

With a proper lactose-free diet guided by a veterinarian, most lactose intolerant cats can enjoy a good quality of life. Their condition is very manageable with simple dietary changes and does not significantly impact long-term health.

Key Takeaways

Many tabby cats are lactose intolerant to some degree. While kittens can typically tolerate milk, lactose intolerance often develops as cats mature. Signs include diarrhea, vomiting, gas, and abdominal pain after consuming dairy products.

Have your vet test your tabby for lactose intolerance if you notice these signs. Eliminating dairy products from their diet is the main treatment. Lactose-free cat foods and supplements are available.

With a proper diagnosis and diet adjustment, lactose intolerant tabby cats can live long, healthy, and happy lives. Be aware of all dairy ingredients in cat foods and treats and monitor your cat’s reaction.
