How to Choose the Right Cat Cave Size for Your Cat
You've found a beautiful wool felt cat cave — the right colour, the right material, the right price. But then comes the question that trips up almost every cat owner: what size do I actually need?
Get the dimensions wrong, and even the most beautifully crafted bed will go unused. Too small and your cat can't turn around comfortably. Too large and it loses the snug, den-like quality cats instinctively seek. Size is the single most important factor in whether your cat will actually use their new bed — and it's the one most owners overlook.
In this guide, you'll learn how to measure your cat correctly, compare cave dimensions by weight and breed, match bed types to sleeping style, and avoid the most common sizing mistakes.

1. Why Cat Cave Size Matters More Than You Think
Cats sleep 12 to 16 hours daily, making their bed one of the most-used items in your home. A cave that is too small restricts movement; one that is too large loses the cosy, den-like quality cats seek. The goal is a space that feels snug without being restrictive.
| Category | Measurement |
|---|---|
| Average Adult Cat Weight | 3 to 6 kg (7 to 13 lbs) |
| Daily Sleeping Time | 12 to 16 hours |
| Curled Sleeping Diameter | 30 to 40 cm |
| Recommended Cave Diameter | 40 to 45 cm |
2. How to Measure Your Cat Before Buying
Breed averages are a starting point, but individual cats vary considerably. Always measure your cat directly before purchasing.
Measure Length
Measure nose to tail base while your cat lies comfortably. This confirms whether the cave opening will allow easy entry and exit.
Measure Curling Diameter
Note the diameter of your cat's body when curled into their favourite sleeping position. This is the single most useful measurement for sizing a cave.
Add a Comfort Allowance
Add 10 to 15 cm (4 to 6 inches) to the curling diameter so your cat can shift position and turn around without feeling cramped.
3. Cat Cave Size Chart by Weight & Breed
Kittens (Under 3 kg)
A small cave with a diameter of 35 to 40 cm (14 to 16 inches) suits young cats and reinforces the sense of security they need as they settle in. Size up slightly to avoid early replacement as they grow.
Average Adult Cats (3 to 6 kg)
A medium cave of 40 to 45 cm (16 to 18 inches) suits most domestic cats and is the best all-round starting point for breeds like the Domestic Shorthair, Burmese, and Abyssinian.
Large Cats (6 to 8 kg)
Look for a large cave in the 45 to 50 cm (18 to 20 inch) range to ensure comfortable entry and exit for breeds like the British Shorthair and Siberian.
Giant Breeds (8 to 12 kg)
Breeds such as the Maine Coon, Ragdoll, and Norwegian Forest Cat require an XL cave of 50 to 60 cm (20 to 24 inches). Standard sizes will not accommodate them comfortably.
| Cat Weight | Cave Size | Diameter (cm) | Typical Breeds |
|---|---|---|---|
| Under 3 kg | Small | 35–40 cm | Kittens, Singapura |
| 3 to 6 kg | Medium | 40–45 cm | Most domestic cats |
| 6 to 8 kg | Large | 45–50 cm | British Shorthair, Siberian |
| 8 to 12 kg | XL | 50–60 cm | Maine Coon, Ragdoll |

Shop Wool Felt Cat Caves by Size →4. Choose Based on Your Cat's Sleep Style
Observe your cat for a few days before purchasing. Sleeping behaviour is one of the strongest predictors of which bed style they will actually use.
The Curler
Cats that sleep tucked nose-to-tail love warmth and enclosed spaces. A traditional cat cave provides the heat retention and security they prefer.
The Burrower
Cats that hide under blankets or squeeze into corners do best in a deep cat cave that mimics a safe den on all sides. This style suits shy or anxious cats especially well.
The Sprawler
Cats that sleep stretched out need room to extend fully. A large open cat bed or lounger is far more appropriate than an enclosed cave for this sleep style.
5. Different Types of Enclosed Cat Beds
Traditional Cat Cave
Suits most cats year-round. The rounded, fully enclosed shape retains warmth in winter and provides a cool retreat in summer. Wool felt cat caves are the preferred material because they are naturally insulating, breathable, and durable — making them one of the longest-lasting bed options available.
Cat Igloo Bed
Features a structured dome for full enclosure. Best for nervous cats or multi-pet households where privacy and noise reduction matter most. The firm felt cat igloo holds its shape over time and gives anxious cats a reliable, consistent retreat.
Covered Cat Bed
A softer canopy design that suits burrowers who find a rigid felt cave too confining. The cover can often be folded back for use as an open bed.
Bunny Cat Cave
Bunny cat caves combine function with a decorative shape, popular for playful kittens and design-conscious interiors. Offers the same warmth and security as a standard felt cave.
| Bed Type | Best For | Enclosure Level |
|---|---|---|
| Traditional Cat Cave | Curlers | Full |
| Cat Igloo Bed | Shy / Anxious Cats | Full + Structured |
| Bunny Cat Cave | Kittens / Playful Cats | Full + Decorative |
| Cat Lounger | Sprawlers | Open |
| Large Cat Bed | Giant Breeds | Semi-open |
| Elevated Cat Bed | Warm Climates / Outdoor | Open |
6. Material Matters: What Makes the Best Cat Cave?
Wool Felt (Recommended)
The gold standard for cat caves. Wool felt offers natural insulation, breathability, and excellent durability. It resists odours, maintains its shape over time, and is crafted from pet-safe materials — creating a cosy, long-lasting retreat your cat will return to again and again.
Velvet
Luxuriously soft and visually refined, though it requires more care to keep clean and can attract pet hair.
Bouclé
A textured, contemporary fabric that is durable and doubles as a design feature in modern interiors.
Twill
Practical and easy to clean — the most affordable option and a sensible choice for kittens or messy cats.
7. Indoor vs Outdoor Cat Beds: Does Size Change?
Core sizing principles apply indoors and outdoors, but outdoor settings add further requirements. An outdoor cat bed must offer weather protection, ground insulation, and ideally an elevated base to lift the sleeping surface above moisture and pests.
For Australian conditions specifically, elevated designs consistently outperform floor beds in terms of hygiene and durability — humidity and rain quickly degrade a bed sitting at ground level.
8. Common Sizing Mistakes to Avoid
- Buying based only on breed. Always measure your individual cat rather than relying on averages.
- Ignoring sleeping position. A sprawler will not use a small cave regardless of quality.
- Choosing a tiny entrance. The opening diameter matters as much as the internal space.
- Not accounting for future growth. Size up slightly for kittens to avoid early replacement.
- Assuming all caves use the same sizing standards. Labels like "medium" vary between manufacturers. Always check actual dimensions in centimetres.
9. Cat Cave Buying Checklist
- ✓ Measure curled sleeping diameter and add 10–15 cm
- ✓ Identify sleeping style: curler, burrower, or sprawler
- ✓ Check the entrance diameter, not just overall size
- ✓ Match cave size to weight using the chart above
- ✓ Choose a material suited to your climate and cleaning routine
- ✓ Confirm indoor or outdoor use
- ✓ Size up slightly for kittens to allow for growth
- ✓ Prioritise comfort and function over appearance

Find Your Cat's Perfect Cave →10. Frequently Asked Questions
Do cats like cat caves?
Most cats take naturally to caves because the enclosed shape mirrors the dens they instinctively seek. Shy and cold-sensitive cats tend to adopt them quickly; confident sprawlers may take a little longer.
What is the best size for an enclosed cat bed?
For an average adult cat (3 to 6 kg), an internal diameter of 40 to 45 cm with a 18 to 20 cm opening works well. Always add 10 to 15 cm to your cat's curled diameter for best results.
How do I get my cat to use a new bed?
Place it where your cat already sleeps. Add a familiar-scented item or a small amount of dried catnip near the entrance to encourage exploration.
How often should I clean a cat cave?
Every one to two weeks under normal conditions. Cats with outdoor access or allergies may need more frequent cleaning. Wool felt requires gentler handling than synthetic materials — spot clean and air dry flat.
Should large breeds use standard cat caves?
No. Maine Coons, Ragdolls, and Norwegian Forest Cats need XL caves of 50 to 60 cm. A standard cave restricts movement and will likely be avoided altogether.
Are wool felt cat caves safe for pets?
Yes. 100% natural wool felt is non-toxic, free from synthetic chemicals, and naturally antimicrobial. Our caves are handmade in Nepal using azo-free dyes and traditional wet-felting methods. Read our full wool felt safety guide.
