Navigating the nutritional needs of a cat diagnosed with cancer can be a complex journey. The Oncology Service emphasizes that a personalized approach is crucial, as a cat’s dietary requirements are influenced by their appetite, the specific type of cancer, the treatment plan, and any other existing health conditions. Cancer and its treatments can significantly impact a cat’s nutritional status, often leading to decreased appetite (hyporexia) or a complete loss of appetite (anorexia). These episodes can be short-term or prolonged, increasing concerns about the cat’s overall well-being. To address this complexity, The Oncology Service collaborates with Cornell University College of Veterinary Medicine to offer individualized nutritional plans. If you wish to explore a nutritional plan for your feline companion, please inform your veterinarian.
Addressing Your Cat’s Nutritional Needs
Numerous online resources offer advice on feline cancer nutrition, but a one-size-fits-all strategy is rarely effective. It’s essential to discern trustworthy information from potentially flawed or harmful advice. Several topics related to feline cancer nutrition have garnered significant attention, and a well-considered approach tailored to your cat’s specific needs is paramount.
The Role of Carbohydrates in Feline Cancer Diets
Some online sources advocate for high-protein, low-carbohydrate, and grain-free diets for all cancer patients. The theory is that reducing carbohydrates limits the primary energy source for cancer cells, with fats and proteins providing energy for the cat. However, there is a lack of robust scientific studies demonstrating a significant impact of carbohydrate levels on survival rates in cats with cancer. While cancer cells utilize glucose and produce lactate, a process that theoretically consumes energy, most cats with cancer do not develop severe weight loss known as cancer cachexia.
As obligate carnivores, cats do not inherently require dietary carbohydrates. Nevertheless, studies suggest that carbohydrates are not detrimental to cats and are unlikely to cause diabetes mellitus or obesity. For cats with certain conditions, such as kidney or gastrointestinal disease, carbohydrates can serve as a vital energy source in low-protein or low-fat diets, helping to manage their condition without exacerbating it. Furthermore, low-carbohydrate diets are often highly palatable to cats, making it challenging to transition them to a diet with higher protein or fat content if medically necessary. Difficulties in finding suitable replacement foods can also arise if a cat becomes a finicky eater while on a low-carbohydrate diet.
Fatty Acid Supplementation for Cats with Cancer
Omega-3 fatty acid supplementation has been a subject of discussion in the context of feline cancer. While a single study evaluated its use in dogs with lymphoma, there are currently no published studies specifically investigating omega-3 fatty acids in cats with cancer. Generally, fatty acids have minimal side effects and might be considered. However, it is recommended to discuss any supplement, including fatty acids, with your oncologist or a veterinary nutritionist before administration.
Introducing a New Diet During Cancer Therapy
If your cat is consuming a regular diet at the start of cancer therapy, it is advisable to continue with that diet throughout the initial treatment cycle. This allows for an accurate assessment of your cat’s nutritional status and their body’s response to the therapy, which will inform any necessary dietary adjustments. It is crucial to discuss all dietary concerns with your oncologist. Developing an individualized nutritional plan may be beneficial. In situations where your cat is experiencing a poor appetite, a more immediate intervention to meet nutritional needs might be required.
Managing Decreased Appetite in Cats
For cats experiencing hyporexia, the primary goal is ensuring adequate caloric intake. Offering a palatable diet that your cat will eat consistently is more important than adhering to a highly specialized diet. Several therapeutic recovery diets may appeal to your cat:
- Hill’s Prescription Diet a/d
- Iams Maximum Calorie
- Royal Canin Recovery RS
- Purina CV Feline Formula
A helpful tip is to warm the food slightly for 5-10 seconds to enhance its aroma, which can encourage eating. Always check the temperature to prevent burns.
Some cats may respond well to variety. Offering a range of foods with different textures, flavors, and consistencies (pâté, shredded, gravy, or kibble shapes) can be beneficial. Understanding your cat’s previous preferences can guide you in selecting foods they might accept when their appetite is reduced.
Incorporating “People Food” into Your Cat’s Diet
In moderation, human food can sometimes stimulate a cat’s appetite. Safe options include:
- Cooked eggs (scrambled or hard-boiled)
- Cooked meats like roasted boneless, skinless chicken, canned chicken, pan-browned ground turkey or beef, or tuna packed in water.
- Chicken or beef broth (ensure it does not contain garlic or onion) can be used as a gravy.
Crucially, NEVER feed your cat the following potentially toxic human foods:
- Baby foods: Often lack sufficient calories and may contain toxic garlic or onion.
- Dairy products: Can cause gastrointestinal upset.
- Raisins or grapes
- Garlic or onions
- Chocolate
- Artificial sweeteners (e.g., xylitol)
When Your Cat Stops Eating Entirely
It is vital not to force-feed your cat, whether by syringe feeding or persistently offering food after they have walked away. This can lead to severe food aversion, making it difficult to manage future appetite issues. Instead, offer small amounts of food every 4-6 hours, allowing your cat to return to it if they show interest.
Consult with your oncologist or primary care veterinarian to determine the appropriate amount and type of food needed to support your cat’s daily activity. If your cat is not consuming a balanced diet for an extended period, vitamin and mineral supplements may be recommended. Should anorexia persist despite efforts to maintain quality of life, a feeding tube may be considered for nutritional support. Feeding tubes are generally well-tolerated and can significantly improve nutritional management. Discussing this option with your oncologist and a nutritionist is essential to determine if it is the right choice for your cat.
