Cat FIV Management: Nutritional Support

Nutritional management plays an important role in supporting immune function and overall welfare in FIV-positive cats throughout their lives.

Key Facts

FIV-positive cats have increased nutritional requirements due to chronic immune activation and infection response
High-quality protein sources support immune function and maintain muscle mass in immunocompromised cats
Raw meat diets are contraindicated in FIV-positive cats due to the risk of bacterial and parasitic infections
Antioxidant-rich foods and supplements may support immune function in FIV-positive cats, though evidence is limited
Maintaining healthy body weight prevents the additional immune challenge of obesity or cachexia
Regular body condition and weight monitoring enables early detection of nutritional problems in FIV-positive cats

Welfare Considerations

Nutritional support for FIV-positive cats is a practical welfare intervention that owners can provide consistently throughout their cat's life. The increased metabolic demands of chronic immune activation mean that FIV-positive cats may require higher protein intake and more frequent feeding than healthy cats. The prohibition on raw feeding, while occasionally contentious among raw diet advocates, reflects a genuine welfare risk: bacterial pathogens in raw meat that immunocompetent cats handle without difficulty can cause serious infections in cats with compromised immune function. Nutritional welfare is one dimension of a comprehensive FIV management approach.

What You Can Do

Feed a high-quality, nutritionally complete commercial cat food meeting AAFCO requirements for adult maintenance
Avoid raw meat, raw eggs, and unpasteurized dairy products due to pathogen risk in immunocompromised cats
Maintain a consistent, high-quality diet rather than frequent protein rotation that may stress the digestive system
Monitor body weight monthly and adjust feeding amounts to maintain healthy body condition score
Discuss vitamin and antioxidant supplementation with your vet — some supplements may benefit FIV-positive cats
Ensure fresh water is always available as adequate hydration supports kidney function and immune health
