Royal Canin Indoor 27 — Detailed Review (Australia 2025)
Who It Suits
Royal Canin’s Indoor 27 Dry Cat Food serves as a great example of how the brand formulates diets for specific lifestyles. It’s developed with the needs of indoor adult cats in mind — typically those who move less, groom more, and may experience stronger litter odour or hairball issues due to limited activity. This formula reflects Royal Canin’s broader approach: tailoring energy levels, fibre types, and mineral balance to match different living environments and life stages. Pet owners can use it as a reference when choosing other Royal Canin varieties designed for weight control, coat health, or digestive comfort.
Ingredients Explained – What’s Inside Royal Canin Cat Food
Royal Canin uses a scientific formulation approach rather than focusing solely on raw meat percentages. Its recipes balance animal proteins (like dehydrated poultry protein and hydrolysed animal protein) with digestible grains (rice, wheat, maize) to provide steady energy and consistent stool quality.
The formula also includes beet pulp, psyllium fibre and prebiotics (FOS) to promote healthy digestion, while fish oil and soya oil deliver essential omega-3 and omega-6 fatty acids for skin and coat health. These are complemented by carefully dosed vitamins and minerals that meet AAFCO standards for complete feline nutrition.
Unlike some “natural” or “grain-free” diets, Royal Canin prioritises nutrient balance and digestibility over marketing claims. Every batch is tested for amino acid profile, fibre ratio and digestibility to ensure predictable results.
Key Benefits (What You Can Expect)
- Odour control: highly digestible L.I.P. proteins reduce undigested residues, helping the litter box smell fresher.
- Hairball management: fibres including psyllium and beet pulp help bind and move hair through the gut.
- Moderate energy: ~13% fat aligns with a lower-activity lifestyle to support a stable weight.
- Urinary support: controlled mineral balance helps maintain a healthy urinary environment—hydration still matters.
Analytical Constituents (AU Label)
| Nutrient | Value | What it means |
|---|---|---|
| Protein | 27% | adequate essential amino acids without pushing calories too high |
| Fat content | 13% | supports energy and coat; moderate for indoor weight control |
| Crude fibre | 4% | part of the hairball strategy and stool quality |
| NFE* (estimated) | ≈43.2% | available carbohydrates to balance energy density |
*Note: NFE (Nitrogen-Free Extract) estimates the digestible carbohydrate fraction, helpful for understanding overall energy balance in a dry cat food.
Real-World Performance: Digestive Health, Coat & Weight
In day-to-day use many pet parents report smaller, firmer stools and less odour within weeks. The fibre blend supports regularity and hair movement, which can reduce coughing or carpet surprises. Calories are sensible for indoor cats; however, playtime and measured portions still matter for weight management.
Pros & Cons
Pros
- Predictable, vet-recommended results for indoor lifestyles.
- High digestibility and strong palatability improve acceptance.
- Clear feeding guide and easy mixed-feeding options with Royal Canin wet cat food.
Cons
- Includes grains; not a grain-free “natural cat food”.
- Premium price versus supermarket products.
- Not a substitute for prescription diets when your vet advises one.
Feeding Guide — Dry & Mixed Feeding
The following feeding guide is provided as a general reference only. Every cat is unique — factors such as body weight, age, activity level, and the amount of treats given can all influence how much food your cat needs each day. Start with the suggested range below and adjust gradually to maintain an ideal body condition score (BCS 4–5/9). Always provide fresh water, and transition slowly over 7–10 days (about 25% new food per stage) to avoid digestive upset.
Dry Only Feeding - Use Indoor 27 as example
| Weight (kg) | Normal Activity | Low Activity |
|---|---|---|
| 3 | 46 g/day | 39 g/day |
| 4 | 57 g/day | 48 g/day |
| 5 | 67 g/day | 57 g/day |
| 6 | 76 g/day | 65 g/day |
Mixed Feeding (Recommended)
Mixing Royal Canin wet cat food improves hydration and satiety. As a simple rule, add one 85 g pouch and reduce the dry portion by ~20%. Explore the wet range in our collection.
How Royal Canin Compares to Other Brands
Compared with natural brands like Feline Natural or Australian favourites like Black Hawk, Royal Canin emphasises science-validated outcomes (odour control, hairball reduction, weight stability) rather than maximising raw meat inclusion or a grain-free positioning. If you want a strictly natural or grain-free diet, a natural brand may feel more aligned; if you value predictable, vet-guided performance and easy portion control, Royal Canin is a strong mainstream choice in Australia.
Who Should Feed Royal Canin Cat Food?
Royal Canin cat food is designed for pet owners who value precision, research-backed nutrition and consistent quality across every meal. Its wide range of formulas means there’s an option for almost every cat — from playful kittens and indoor loungers to long-haired breeds and seniors with sensitive digestion.
- Cat owners seeking vet-recommended nutrition with proven results in digestive health, coat condition and weight control.
- Indoor cats that need hairball reduction, odour control and balanced calorie intake.
- Cats with sensitive stomachs or selective appetites that respond well to high-digestibility proteins.

Price and Value for Money in Australia
Pricing varies by retailer and bag size. The table below shows typical per-kg ranges to help you compare natural cat food, Royal Canin, and supermarket cat food. Use this as a guide only. Larger bags and mixed feeding (dry + wet) can lower the average cost per meal.
| Segment | Typical per-kg price (AUD) | What you’re paying for | Who it suits |
|---|---|---|---|
| Natural cat food (e.g., Ziwi Peak style, air-/freeze-dried) | $25–$45+/kg (can be higher for air-/freeze-dried equivalents) | High meat inclusions, minimal processing, “whole-prey” positioning; often grain-free. | Owners prioritising minimally processed diets and willing to pay a premium. |
| Royal Canin (Indoor 27 as reference) | $12–$22/kg (larger bags better value) | Science-validated outcomes: odour & hairball control, digestibility, consistent quality and clear feeding guides. | Indoor families wanting predictable, vet-recommended results and easy portion control. |
| Supermarket cat food | $5–$12/kg | Lower price point; variable meat content; fewer targeted features. | Strict budgets or short-term feeding; check labels for protein quality and feeding amounts. |

FAQs — Royal Canin Indoor 27 (Australia)
Is Royal Canin Indoor 27 suitable for desexed indoor cats?
Yes. Desexed cats often have lower energy needs. Indoor 27’s moderate fat and clear portions help maintain a healthy body condition; monitor weight monthly and adjust grams accordingly.
Can I use Royal Canin for sensitive stomach cats?
Many sensitive cats respond well to high-digestibility proteins. If vomiting, diarrhoea or soft stools persist, ask your vet about a veterinary gastrointestinal formula.
Royal Canin vs natural cat food — which is better?
They solve different goals. Natural brands emphasise minimally processed meat; Royal Canin emphasises digestibility studies, fibre design and consistent results. Choose based on your cat’s needs and your feeding philosophy.
How do I transition from supermarket cat food?
Mix 25% new food for 2–3 days, then 50% for 2–3 days, then 75% for 2–3 days, watching stool quality and appetite. Keep water available and avoid extra treats during the switch.
Can I mix Royal Canin dry with other wet foods?
Yes, but keep nutrients balanced. If you use a non-Royal Canin wet, reduce dry grams to avoid excess calories. For simplicity, pair Indoor 27 with Royal Canin Indoor wet pouches.

Prices vary by size and retailer, but many shoppers see $12–$22/kg for dry food when buying larger bags. See the price comparison table above for context.
When should I choose a Veterinary Diet instead?
If your cat has recurrent urinary signs, chronic GI issues, allergies, kidney disease or your vet recommends a prescription formula, use the specific Royal Canin Veterinary Diet instead of a retail product.
Is Royal Canin good for long-hair breeds like Ragdoll?
Yes. Indoor 27 helps with hairball passage. You can also consider breed-specific formulas (e.g., Ragdoll) for kibble shape and micronutrient tweaks designed for long-hair coats.
