Size Regulations for Your Cattery

Understanding Cattery Size Requirements

When embarking on a cattery project, understanding the required dimensions for your cat accommodation is one of the first practical hurdles. Local authorities set specific minimum sizes for pens and chalets, and meeting these standards is a condition of being granted a licence to operate.

These requirements exist to ensure cats have adequate space during their stay. Before you begin designing or purchasing units, you should obtain the relevant documentation from your local council. This is usually called something like "Animal Boarding Establishment Conditions" or similar.

While most councils across the UK follow broadly similar guidelines, there can be local variations. Your council's licensing team will be able to provide their specific requirements, and this should be your first point of contact before committing to any building work or equipment purchases.

What the Regulations Typically Cover

Size regulations for catteries usually specify minimum floor space, height, and the dimensions of sleeping areas. These measurements are designed to give cats enough room to move around, stretch, and separate their sleeping and toilet areas.

Most local authority conditions will require:

• A minimum floor area for the main unit, though this varies among councils and increases when housing multiple cats from the same household
• Adequate height for cats to climb and for staff to work comfortably
• A separate or raised sleeping area of specified dimensions
• Enrichment considerations such as scratching posts, elevated platforms, or viewpoints to support feline welfare

The exact figures vary considerably between local authorities, so always check with your own council rather than assuming national standards apply. Some councils have updated their conditions more recently than others, and requirements may have changed.

You can usually find licensing information on your council website, or you can contact the environmental health or licensing department directly. For general guidance, GOV.UK provides information on the Animal Welfare (Licensing of Activities Involving Animals) (England) Regulations 2018. Scotland, Wales, and Northern Ireland operate under separate legislative frameworks with their own specific requirements, so cattery owners in those nations should consult their devolved government guidance directly.

Thinking Beyond Minimum Standards

Meeting the minimum size requirements will allow you to obtain a licence, but there are good reasons to consider building larger units if your space and budget allow.

Working in a unit built to the bare minimum can be awkward. Cleaning, feeding, and handling cats requires room to move, and many cattery owners find that additional floor space and headroom make daily tasks more manageable. Whether this translates to meaningful time savings depends on your specific layout and workflow.

Cats themselves may benefit from additional space. While the minimum standards are considered acceptable for short stays, larger units can make the boarding experience less stressful, particularly for cats accustomed to having the run of a house. However, a well designed smaller unit with good enrichment features can sometimes serve cats better than a larger but bare space.

Bigger units do mean fewer cats can be accommodated in the same footprint. The right balance between unit size and capacity will depend on your site constraints, target market, and business model. It is worth working through the numbers for your specific situation before finalising plans.

Practical Considerations for Design

Beyond the raw measurements, think about how each unit will function in practice. Raised sleeping areas are a standard requirement and give cats a place to rest away from the floor. These shelves or pods need to be sturdy, easy to clean, and positioned so they do not obstruct access for cleaning or cat handling.

Headroom matters more than you might expect. Spending time in a low ceiling space quickly becomes tiring, and it makes tasks like changing bedding or checking on a cat at the back of a unit more difficult than it needs to be.

Ventilation, lighting, and drainage are also covered by most licensing conditions, though the specifics fall outside pure size regulations. Your council will advise on the full range of requirements when you apply for your licence or request pre application guidance.

If you are unsure about any aspect of cattery design and construction, consider consulting with a specialist cattery builder or speaking to experienced cattery owners. The Chartered Institute of Environmental Health publishes detailed construction and welfare guidance that many find useful. International Cat Care, formerly the Feline Advisory Bureau, also offers resources on cat accommodation standards.
