Functional dry cat food
A functional dry cat food is formulated around a specific need rather than being a general adult maintenance recipe — urinary health and digestive support are the two most common examples in our range, such as Purina One Adult Cat Urinary Health Chicken.
Urinary health formulas
A urinary-focused recipe like Purina One Adult Cat Urinary Health Chicken is typically formulated to help maintain a healthy urinary tract environment, often alongside encouraging good water intake, since urinary problems in cats are linked to a mix of diet and hydration. It's a general wellbeing formulation rather than a treatment for an existing urinary problem.
If your cat has had a urinary issue before, or is showing signs like straining, frequent visits to the litter tray, or blood in their urine, that needs a vet visit rather than a food change alone — urinary problems in cats can become serious quickly, particularly in male cats.
Digestive support formulas
Digestive-focused recipes are built around ingredients intended to support gut health, alongside supplements like Bugalugs Pre & Probiotic Digestive Powder or Supreme Science Selective Supplements Digestive Care that can be added to any food rather than requiring a switch to a dedicated recipe.
A cat with occasional mild digestive sensitivity may do well simply moving to a digestive-support recipe, but ongoing vomiting, diarrhoea or weight loss should be checked by a vet rather than managed through diet alone, since those signs can point to something needing proper investigation.
Choosing and switching to a functional food
Match the food to an actual need your cat has rather than choosing one speculatively, since a functional food formulated for a problem your cat doesn't have offers no particular benefit over a good general recipe.
Introduce any functional food gradually over a week or so, the same as any new food, and if you're switching because of a specific health concern, it's worth mentioning the change to your vet so they know what your cat is currently eating.

Common questions
- What does 'functional' mean on a cat food label?
- It generally means the recipe is formulated around a specific need, such as urinary or digestive health, rather than being a general adult maintenance food. It's a positioning term used across the pet food trade rather than a regulated one, so check what the specific food is actually formulated for.
- Can a urinary health food treat a cat that already has urinary problems?
- No, these foods support general urinary wellbeing rather than treat an existing problem. A cat showing signs like straining, frequent litter tray visits or blood in their urine needs to see a vet promptly rather than relying on a food change alone.
- Should I feed a functional food if my cat doesn't have a specific problem?
- There's little benefit to feeding a functional food formulated for a need your cat doesn't have — a good general adult recipe is usually the more sensible choice. Move to a functional food when there's an actual reason to, ideally with your vet's input.
