One way to stop cats pooping in the garden is to give them their very own outdoor cat litter box. A cat litter box provides your little Leo with an alternative garden throne. It allows them to satisfy their natural instincts without scrapping in the vegetable patch. Even if it's raining, a hooded litter tray can be used, so it helps minimise accidents indoors. An outdoor loo can also reduce the odour and mess that comes with an indoor tray – now, that's got to be a pawsitive.

If you love your garden and tire of cats treating it like a personal excavation site, an outdoor cat litter box could put an end to manicured flower beds getting mangled. These al fresco feline facilities take the form of a hooded all-in-one litter trays or a wooden box with a tray inside. Typically, they are waterproof and spacious. They minimise the odour of faeces in the garden and provide a private sanctuary for skittish kitties to do their business.

When it comes to positioning the cat litter box, place it away from your cat's food and water. In Vicky Halls' article on cat litter trays for Cats Protection, she advises: "They should be in discreet corners or adjacent to walls so that the cat has full view of approaching danger but is protected from behind." Other than that, treat an outdoor cat litter box with the same cleaning routine as you would an indoor box; unfortunately, the self-cleaning cat litter box for outdoors has yet to be invented.

If you're conscious to find the best eco cat litter trays, several cat litter boxes in this guide are made from sustainable wood sources. Aesthetically, a wooden box will blend in with the garden more so than a plastic model. But do bear in mind that wood will need treating over time.

Outdoor cat litter box FAQs

What do I need to know about maintaining a clean cat litter box?

Best practice for managing a litter tray involves key steps to ensure cleanliness, odour control and the wellbeing of your cat:

Size: A litter tray should be large enough for your cat to comfortably turn around and dig. General rule of thumb is one and half times the length of your cat.

Location: Place the litter tray in a quiet and accessible area where your cat feels safe. Avoid placing it near their food and water bowls.

Type of litter: Choose a litter that your cat prefers and that works well for odour control. Clumping litter is popular as it makes cleaning easier, but some cats prefer non-clumping litter. Experiment to find what works best for your cat.

Depth of litter: Maintain a depth of litter around 3–4cm. However, if your cat is peeing a lot, Vicky Halls advises: "the depth should be sufficient to soak up the larger than normal amount of liquid that is deposited at any one time."

Cleaning: Scoop the litter tray at least once a day to remove waste and clumps. Thoroughly clean the tray with mild soap and hot water on a regular basis, replacing the litter entirely every week. For more information, read our guide on how often should you change cat litter.

Number of trays: For households with multiple cats, provide one litter tray per cat plus an extra one to prevent competition and territorial disputes.

Vicky Halls advises, "When cats go to the toilet outdoors they generally prefer separate locations for urination and defecation. So if you were to simulate the ideal facilities indoors you would provide two trays for one cat."

Odour control: Consider using odour-absorbing litter to help neutralise smells. Regular cleaning and proper ventilation also help control odour.

What type of cat litter works best?

The best type of litter often depends on the preferences of both your cat and you. Here are some common types of litter and their characteristics:

Clumping clay litter forms clumps when it comes into contact with moisture, making it easy to scoop out waste. It's popular for its convenience and odour control.

Non-clumping litter: Unlike clumping litter, non-clumping litter absorbs urine but doesn't form tight clumps. It's generally less expensive but requires more frequent changes.

Silica gel crystals are small, absorbent crystals that lock in moisture and control odour effectively. It's low-dust and can last longer than traditional clay litter.

Eco-cat litter is made from natural materials. It's biodegradable and an eco-friendly option. They are often flushable and decompose naturally. However, some cats may take time to adjust to the texture and smell.

Pellet litter is made from compressed sawdust or recycled paper. It's absorbent and controls odour well, but some cats may not like the texture.
