Introduction
Cancer is a devastating diagnosis for any pet parent, and it can be particularly challenging when it comes to managing our feline friends’ nutritional needs during this difficult time. As a pet science blog author, I’ve had the opportunity to delve into the intricacies of feline nutrition, especially in the context of cancer. In this article, I’ll share insights on how to support your cat’s health through proper nutrition, drawing from both scientific research and my own experiences.
Understanding Cancer Cachexia
Cancer cachexia is a unique form of weight loss that affects cats with cancer. Unlike starvation, where the body primarily loses fat, cachexia leads to the loss of both muscle and fat tissues. This condition is exacerbated by the fact that cats with cancer often experience a decreased appetite, which only adds to the severity of malnutrition.
Causes of Weight Loss in Cats with Cancer
Several factors contribute to the weight loss seen in cats with cancer:
- Decreased Appetite: Cancer can cause nausea, leading to a reduced interest in food.
- Direct Tumor Effects: Tumors in the mouth, throat, or digestive tract can make eating difficult and may cause vomiting or diarrhea.
- Chemotherapy Side Effects: Chemotherapy drugs can alter a cat’s sense of smell or taste, leading to food aversion.
- Radiation Therapy Impacts: Radiation can affect saliva production and cause mouth or digestive issues.
- Altered Metabolism: Cancer cells have a preference for simple carbohydrates, increasing the body’s caloric needs.
- Body’s Response to Cancer: The body may produce substances that affect appetite and muscle mass.
Recommended Diets for Cats with Cancer
To combat cancer cachexia, it’s crucial to provide a diet that is:
- Energy Dense: High-calorie foods are essential to ensure the cat receives enough energy, even if eating small amounts.
- High in Fat: Since tumor cells are less likely to use fat for energy, a diet with 25-40% fat on a dry matter basis is recommended.
- Moderately High in Protein: To counteract muscle loss, protein levels should be 40-50% on a dry matter basis, provided the cat’s kidney and liver function are normal.
- Low in Carbohydrates: Limiting carbohydrates to less than 25% of the food on a dry matter basis can theoretically starve tumor cells.
Calculating Nutrients on a Dry Matter Basis
To ensure you’re providing the right balance of nutrients, it’s important to understand how to calculate them on a dry matter basis. This can be done by looking at the Guaranteed Analysis on the food container, subtracting the moisture content from 100, and then dividing the nutrient value by the dry matter to get the percentage.
Added Nutrients
Some nutrients can be beneficial for cats with cancer:
- Omega-3 Fatty Acids: These can help reduce cachexia and may have a direct effect on tumor cells.
- Arginine: This amino acid can benefit the immune system and may influence tumor growth.
- Vitamin B12: Cats with intestinal cancer may develop a deficiency, which can be addressed with injections.
Increasing Food Intake
Ensuring your cat eats is just as important as what you’re feeding them. Here are some strategies to increase food intake:
- Increase Moisture: Cats often prefer foods with higher moisture content.
- Increase Aroma: Warming canned food can enhance its aroma.
- Assure Freshness: Offering multiple small meals throughout the day can help ensure freshness.
- Try Novel Foods: Offering new foods or changing feeding locations may entice your cat to eat.
- Avoid Medication Association: Do not mix medications with food or water, and avoid medicating around meal times.
- Make Eating Easy: Ensure food bowls are easily accessible and consider removing any eating barriers, like Elizabethan collars, during meal times.
- Avoid Feeding During Nausea: Do not force-feed a nauseated cat, as this can lead to food aversions.
- Administer Appetite Stimulants: These can be used as a last resort to stimulate appetite.
Feeding Tubes
In cases where a cat refuses to eat, feeding tubes can be a lifesaving option. They are well-tolerated by cats and can help maintain normal digestive function.
Conclusion
Nutrition plays a vital role in a cat’s response to cancer therapy and overall quality of life. By providing a diet rich in fat and protein and employing strategies to increase food intake, we can help counteract the effects of cancer cachexia. Always consult with your veterinarian to ensure the best possible care for your feline companion.
