Answer-first
Can I mix wet and dry cat food?
Yes — mixing is common and lets you combine wet food's hydration (it's ~70% water vs ~10% in dry) with dry food's convenience and lower cost. Just count BOTH toward the daily calorie total so the combo doesn't quietly overfeed, and don't leave the wet portion sitting out.Fact
Mixing is a valid strategy, not a compromise — the main rules are total-calorie discipline and wet-food food safety.
Applies to: Healthy cats on maintenance feeding. Cats on a therapeutic diet follow the vet's plan (mixing may break it).
Steps
Why mixFact
- Wet food is ~70% water, dry ~10% — mixing raises hydration over dry-only
- Dry is cheaper and easy to portion; wet adds moisture and palatability
- A good middle ground for dry-fed cats you want to hydrate more
Do it rightFact
- Count wet + dry together toward the daily calories (don't just add wet on top)
- Wet food shouldn't sit out — discard it after 1–2 hours at room temperature
- Serve wet fresh; keep dry available separately if free-feeding a portion
Watch the scaleProfessional guidance
- Mixing is where accidental overfeeding hides — weigh monthly
- Transition gradually if it's a new format (see food-transition page)
- On a prescription diet? Ask the vet before mixing anything in
Normal vs keep-watching
Normal: A cat that eats a measured wet+dry combo and holds a steady weight.
Keep watching: Total daily portions (both formats) and monthly weight.
When to contact a vet. A cat on a therapeutic diet, or one that gains/loses weight on a steady combo, is a vet conversation — this page never overrides a prescribed diet.
What changes this answer
- Therapeutic diet (vet decides)
- Hydration goal (more wet)
- Budget (more dry)
Common mistakes
- Adding wet on top of full dry rations
- Leaving wet food out for hours
- Mixing into a prescription diet without the vet
- Not weighing to catch creep
