Kitten Shakes After Drinking Milk

You must have noticed that your adorable furry friend is experiencing shakes or tremors after taking milk, you may be wondering what could be causing this behavior and what steps to take.

While milk is often associated with cats, it is important to note that not all felines can tolerate it. Some kittens, in particular, may experience an adverse reaction to the milk due to lactose intolerance.

Like humans, kittens can also produce enzymes known as lactase, which can help break down lactose in milk. However, as kittens grow older, the production of lactase tends to drop or decrease, thereby making it difficult for them to digest lactose seamlessly.

This can result in various symptoms, including shaking or trembling after consuming milk. There are also other potential causes for these shakes, such as food allergies or reactions to certain compounds in milk.

It is crucial to observe your kitten closely and consult a veterinarian to determine the exact cause of these shakes and ensure the well-being of your furry companion.

In this article, we will explore some practical steps you can take if your kitten shakes after consuming milk and uncover ways to ensure that your kitten remains healthy and happy under your care.

An Overview Of Lactose Intolerance In Kittens

Lactose intolerance is a condition that affects kittens, just like it does with adult cats and humans. Lactose is a type of sugar found in milk and other dairy products. Kittens, like all mammals, possess an enzyme called lactose, which helps break down lactose and digest it properly.

however, as kittens grow older, their production of lactase tends to decrease, resulting in lactose intolerance. When kittens consume milk or dairy products, the lactose present in these foods cannot be properly digested and absorbed by their digestive system.

Instead, it remains undigested in the gut, leading to various symptoms such as diarrhea, bloating, gas, and in some cases, stomach discomfort or even vomiting. As a result, it’s generally recommended to avoid feeding kittens with cow’s milk and other dairy products.

It is best to feed them the s[pecialized kitten formula that is lactose-free and fulfills their nutritional needs. These formulas are readily available and provide all the necessary nutrients for healthy growth and development.

Other Potential Reasons For Shaking After Drinking Milk

While lactose intolerance is a common cause of shakes or other symptoms after consuming milk in kittens, there can be other potential factors to consider. Here are a few possibilities;

1. Overfeeding

Providing too much milk to a kitten can lead to an upset stomach, resulting in shakes or digestive issues. It’s important to follow the appropriate feeding guidelines for kittens to ensure they receive the right amount of milk.

2. Milk Allergy

Although less common than lactose intolerance, some kittens may have an allergic reaction to certain proteins found in milk. This can lead to shakes, skin rash, itching, or even difficulty breathing.

3. Infection Or Illness

Shakes in kittens can also be a sign of an underlying infection or illness. It’s essential to monitor for any other accompanying symptoms, such as fever, lethargy, loss of appetite, or changes in behavior. In such cases, it is advisable to seek veterinary attention promptly.

4. Hypoglycemia

Low blood sugar levels in kittens can cause shaking or trembling. It’s possible that milk alone might not be providing enough nutrients and calories to maintain stable blood sugar levels.

In these cases, it may be necessary to consult a veterinarian to adjust the kitten’s diet accordingly.

5. Other Digestive Issues

Shakes after consuming milk could be related to digestive issues such as an upset stomach, indigestion, or even an intestinal infection. These conditions can occur due to various factors and may require veterinary intervention for accurate diagnosis and appropriate treatment.

What To Do When Your Kitten Shakes After Drinking Milk

If your kitten experiences shaking after drinking milk, it is important to take the following steps;

1. Immediately Remove Leftover Milk

If your kitten starts shaking or showing discomfort after drinking milk, remove the milk source immediately. This will help prevent further ingestion of milk that could worsen their symptoms.

2. Monitor Your Kitten

Keep a close eye on your kitten and observe its behavior. Note any additional symptoms they may be experiencing, such as diarrhea, vomiting, or lethargy. If the shaking persists or if other concerning symptoms develop, contact your veterinarian for advice.

3. Offer Water

Provide your kitten with fresh water to help ease any potential discomfort and keep them hydrated. It’s important to ensure they have access to water at all times, especially if they are experiencing diarrhea or vomiting.

4. Consult With a Veterinarian

If the shaking continues or if your kitten displays any worrisome symptoms, it is recommended to seek veterinary attention. They can assess your kitten’s health, provide a proper diagnosis, and offer appropriate guidance or treatment options.

5. Consider Alternative Feeding Options

If your kitten displays signs of lactose intolerance after consuming milk, it’s best to avoid giving them milk altogether. Instead, opt for a specialized kitten formula that is lactose-free and designed to meet their nutritional needs.

6. Follow Dietary Recommendations

Work with your veterinarian to establish a suitable diet for your kitten, taking into consideration any potential dietary restrictions or allergies they may have. They can recommend the best food options to ensure your kitten receives optimal nutrition without any adverse reactions.


If your kitten experiences shaking after drinking milk, it is important to address the issue promptly. While the most common cause is lactose intolerance, other factors such as overfeeding, milk allergy, infection or illness, hypoglycemia, or other digestive issues could be contributing to the symptoms.

To ensure your kitten’s health, it is advisable to remove the milk source, monitor their behavior, offer water for hydration, and consult with a veterinarian if the shaking persists or if additional concerning symptoms arise.

Working closely with a veterinarian will help determine the underlying cause and provide appropriate guidance for your kitten’s specific needs.
