Catio Alleyway Enclosure (3-Sided Lean-to) Slim Outdoor House 3.7m x 1m (12 x 3ft)

Create a Safe Outdoor Sanctuary: Premium Wooden Catio Enclosure

Give your indoor cats the outdoor adventure they crave without the worry. While cats naturally love to bask in the sun and watch the world go by, free-roaming exposes them to risks like busy traffic, territorial neighborhood cats, and predators—while also posing a threat to local wildlife.

Our premium wooden catio (cat patio) bridges the gap, providing a highly secure, enriching outdoor cat enclosure that fits perfectly onto your patio, garden lawn, or side return.

Promote Feline Health & Well-Being

More than just a cage, a well-designed catio acts as a stimulating outdoor sanctuary. Whether your cat wants to lounge in the afternoon sun, climb to new heights, or simply enjoy the fresh air, this enclosure delivers a 360-degree sensory experience. Safe outdoor access is proven to reduce feline boredom and anxiety, encourage physical exercise, and promote a healthier, happier cat.

Uncompromising Security & Craftsmanship

Every element of this outdoor cat house is designed with your pet’s safety and the enclosure's longevity in mind:

• Fox-Proof 16G Galvanized Mesh: Flimsy chicken wire doesn't cut it against determined predators. Our enclosures feature heavy-duty 16-gauge mesh that is completely fox-proof. You can choose the exact mesh size to suit your environment (1" x 1", 1/2" x 1/2", 1/2" x 1", or 2" x 2")—smaller gauges are excellent for keeping out tiny garden pests and wild birds.
• Heavy-Duty Pressure-Treated Timber: Built from robust 2" x 2" wood that has been pressure-treated to resist rot, fungal decay, and harsh UK weather conditions.
• 100% Pet-Safe Finish: The wood is treated with an animal-friendly preservative, ensuring that even if your cat decides to nibble or scratch the frame, they remain completely safe.
• Convenient Human Access: Includes a fully integrated, full-height walk-in door panel featuring a secure latch. This makes stepping inside to feed your cats, clean the enclosure, or simply spend quality time with them entirely hassle-free.

Do I need planning permission for this catio in the UK?
In most cases, no. Because this is a temporary, non-permanent timber structure for your back garden, it typically falls under permitted development. However, if you live in a listed building, a conservation area, or have strict HOA rules, we always recommend double-checking with your local council.

Is the mesh strong enough to keep foxes and predators out?
Absolutely. We use heavy-duty 16-gauge (16G) galvanized wire mesh—which is significantly thicker and stronger than standard chicken wire. It is entirely fox-proof, ensuring your cats are completely safe from outdoor predators.

Can the catio stay outside all year round?
Yes! The frame is built using robust 2" x 2" pressure-treated timber that is designed to withstand harsh UK weather—from heavy winter rain to summer heat. It is also finished with a 100% animal-friendly stain to protect the wood without posing any risk to your pets.

What kind of surface should I put the catio on?
For the highest level of security, we recommend installing the catio on a flat, hard-standing surface such as a concrete patio, paving slabs, or wooden decking. You can place it on leveled grass or soil, but you will need to monitor your cats to ensure they don't try to dig underneath the frame.

How difficult is it to assemble?
Not difficult at all! The catio arrives flat-packed in manageable panels and is designed for stress-free, DIY self-assembly. All necessary screws are included in the box. You will simply need a standard power drill or screwdriver and a spare afternoon to put it together.

Can I connect the catio directly to my house or a cat flap?
Yes, many of our customers position the enclosure directly over a back door, patio door, or a window fitted with a cat flap. This allows your indoor cats to safely come and go as they please without you needing to manually let them in and out.

How does the 3-sided lean-to model attach to my house?
The 3-sided lean-to model is specifically designed to sit flush against your home’s exterior brickwork or siding, utilizing your house wall as the fourth side of the enclosure. This is the perfect solution for completely enclosing a back door, patio doors, or a window fitted with a cat flap, creating a seamless and secure transition from indoors to outdoors. To ensure a tight, predator-proof seal, you will need to safely secure the timber frame directly to your exterior wall using appropriate masonry wall plugs and screws (wall fixings are not included, as requirements vary depending on your home's specific construction).
