TL;DR
- Purina ONE Tender Selects Blend (Adult) — Guaranteed Analysis (as fed): Protein 34%, Fat 15%, Fiber 2%, Moisture 12%. (Purina product sheet / PDF).
- We converted each product to dry-matter (DM) basis and estimated carbs (NFE) by difference (common ash assumptions where brands do not list ash). On a DM basis:
- Purina ONE Tender Selects: Protein 38.64%, Fat 17.05%, Carbs 32.95%, Fiber 2.27%.
- Purina Pro Plan Chicken & Rice: Protein 40.91%, Fat 18.18%, Carbs 29.55%, Fiber 2.27%. Bone a Patreat
- IAMS ProActive Health Adult: Protein 35.56%, Fat 16.67%, Carbs 36.67%, Fiber 3.33%. A.W. Brown Pet & Garden Store
Why Compare on a Dry-Matter Basis?
“Guaranteed Analysis” on the bag is as-fed, which includes variable moisture. Converting to dry-matter removes moisture differences so you compare the true macronutrient ratios cats actually get per gram of nutrients. Use DM when assessing protein, fat, carbs and fiber for diet decisions.

Dry-Matter Nutrient Table
| Product (DM basis) | Protein (%) | Fat (%) | Carbs (NFE) (%) | Fiber (%) |
|---|---|---|---|---|
| Purina ONE Tender Selects (DM) | 38.64 | 17.05 | 32.95 | 2.27 |
| Purina Pro Plan Chicken & Rice (DM est.) | 40.91 | 18.18 | 29.55 | 2.27 |
| IAMS ProActive Health Adult (DM est.) | 35.56 | 16.67 | 36.67 | 3.33 |
Method note: Carbs (NFE) were calculated by difference (100 − protein − fat − fiber − moisture − ash) on an as-fed basis, then converted to DM. Ash assumptions: 8% for Purina products where ash wasn’t listed; 7% for IAMS (label listed). Where brands list ash, we used the listed value. All calculations and charts are reproducible.
How to Interpret These Results
Carbohydrates: All dry kibbles contain carbs; IAMS had the highest estimated NFE on DM in this trio. If you’re minimizing carbs, consider rotating with a high-protein wet food.
Protein-focused households: If you prioritize higher protein (for lean mass, active cats), Purina Pro Plan shows the highest protein on DM. Purina ONE is close behind and still strong for maintenance. Bone a Patreat+1
Fat & calorie density: Pro Plan is also highest in fat (DM), which increases palatability and calorie density—helpful for picky or underweight cats, but feed portions carefully for indoor/less active cats. Bone a Patreat
Fiber & hairball/weight control: IAMS lists higher fiber (as-fed 3%, DM ~3.33%), which can help hairball control and satiety for indoor cats; Purina ONE has lower fiber so might be better if you prefer lower-carb, lower-fiber kibble. A.W. Brown Pet & Garden Store+1
Buyer Scenarios
- Active/outdoor adult cats: Purina Pro Plan (higher protein & fat on DM) — supports energy and lean mass. Bone a Patreat
- Everyday balanced maintenance (value + real chicken): Purina ONE Tender Selects — solid protein and palatability with recognizable ingredients like chicken first. ピュリナ
- Indoor/hairball-prone or weight-control cats: IAMS ProActive (higher fiber, lower carbs) — consider pairing with measured portions and vet guidance. A.W. Brown Pet & Garden Store
FAQs
Q: Is Purina ONE Tender Selects a complete and balanced food for adult cats?
A: Yes. Purina’s product sheet indicates it provides complete and balanced nutrition for adult maintenance (AAFCO-substantiated feeding tests). Always follow feeding guides and consult your vet for special health needs. ピュリナ
Q: Why are carbs listed by difference sometimes inaccurate?
A: When brands don’t publish NFE (carbs), we calculate by difference and must assume ash. That creates small estimation error; listed carbohydrate values from the brand are always preferred.
