Hill’s food sensitivities and skin care for cats
Food sensitivities and skin care
Hill’s d/d and z/d cat foods work differently based on their protein sources to manage food sensitivities and intolerances. z/d uses highly hydrolyzed protein, where the protein molecules are broken down so small they are not recognized by the immune system. d/d uses novel proteins, meaning proteins a cat is unlikely to have been previously exposed to, which helps prevent an allergic reaction. Both formulas contain essential fatty acids and antioxidants to support skin and immune health.


How z/d works :
Highly hydrolyzed protein:
- The protein is broken down into tiny pieces, so the cat’s immune system doesn’t recognize it as a potential allergen.
Novel protein source:
- The formula uses a carefully selected source of protein and carbohydrate that the cat is unlikely to have reacted to before.
ActiveBiome+ Technology:
- Includes a blend of prebiotics to support gut health, which helps with digestion and stool quality
Essential fatty acids and antioxidants:
- Support skin health and the immune system.
How d/d works:
Novel protein:
- Uses a protein source that the cat has not been previously exposed to, like duck, venison, or fish, to help avoid allergic reactions
Highly levels of essential fatty acids:
- Helps soothe inflamed skin and improve the skin barrier.
Antioxidants:
- Helps support the immune system and protect against cell damage from free radicals.

Food sensitivities and skin care
Hill’s d/d and z/d cat foods work differently based on their protein sources to manage food sensitivities and intolerances. z/d uses highly hydrolyzed protein, where the protein molecules are broken down so small they are not recognized by the immune system. d/d uses novel proteins, meaning proteins a cat is unlikely to have been previously exposed to, which helps prevent an allergic reaction. Both formulas contain essential fatty acids and antioxidants to support skin and immune health.


How z/d works :
- The high concentration of omega-3 fatty acids, particularly EPA from fish oil, helps to soothe inflamed tissues and relieve joint pain.
