FunXplore Cat Houses, Catios & Outdoor Pet Shelters

FunXplore's walk-in catios give you three distinct connection options: window mount via back-panel removal, pet flap alignment through a ground-floor door, and freestanding placement anywhere in the yard. Which method you choose determines where you place the catio, how you orient the asphalt roof, and which model's door count actually matters for your setup.

Window Mount — The Most Popular Setup

The PD-1029 is designed so the back panel removes entirely, letting the open frame align flush with a double-hung window. Your cat pushes through the window, steps into the catio, and can access all 4 tiers and 30.05 ft² of interior space without ever touching the ground. Measure your window rough opening before ordering — the catio's back opening needs to clear your window frame on both sides. Most standard double-hung windows work; bay windows and casements need a custom adapter tunnel between the sill and the catio frame.

The 6 ground-floor side doors on the PD-1029 are specifically designed for this scenario. Four of them give senior cats or kittens low-entry access at ground level while the main window connection handles your other cats. This is also useful if you ever want to connect a cat tunnel from the catio to a second enclosure.

Pet Flap Connection

If your cat door is in a wall or door panel rather than a window, align one of the PD-1029's 6 side doors with the flap opening. The ground-floor doors are sized for this — a cat flap tunnel bridging the gap between the structure and your exterior wall is all you need. For the PD-1027 (5-door version at 62.6"L), the 5-door configuration gives you enough placement flexibility to line up one access point regardless of where your pet flap exits.

Freestanding Placement

Not every setup needs a house connection. Freestanding catio placement works well for feral cat caretakers, multi-cat households wanting a designated outdoor enclosure, and anyone whose home layout makes window mounting impractical. For freestanding use, surface type matters more than you'd expect.

• Grass: Best natural option — the catio base sits flush, drainage is built-in, and the structure stays cooler in summer. Stake the corners if you're in a high-wind area.
• Concrete or patio pavers: Perfectly stable, easy to hose down, but make sure the base isn't sitting in a low spot that pools after rain. The PD-1027 and PD-1029 have wooden base frames — standing water against wood shortens its life.
• Wood decking: Fine, but check that your deck boards can bear the load. The PD-1029 ships in 2 packages and weighs 132.6 lbs assembled. Distribute that across deck joists, not just the surface boards.

Asphalt Roof Orientation

Both the PD-1029 and PD-1010 feature what FunXplore calls a flip-friendly asphalt roof — the panel can be installed facing front or back depending on the direction your primary rain comes from. This matters more than it sounds. Most backyards have a prevailing rain angle based on wind direction. Orienting the roof panel so the lower edge faces into the rain means water sheds away from the front door rather than dripping directly over the entry point. Before final assembly, stand at the planned install location during or just after rain and note which direction water runs. Set the roof overhang toward that side.

Human Access During Cleaning

Both walk-in models have full-height front doors — 67" on the PD-1029, 69.3" on the PD-1027. Most adults can step in without stooping. The practical difference: the PD-1027's slightly taller door matters if you're over 6'1" and plan to do regular cleaning inside the structure. For the PD-1010 wheeled tower at 70.9"H, you won't step inside — you access the interior through the 2 lockable doors, and the removable middle floor slides out for cleaning without disassembly. Plan for roughly 10–15 minutes of cleaning time per week for a 4–6 cat household using a walk-in catio.

4-Tier Wheeled Catio Setup Specifics

The PD-1010 at 31.5×31.5" has 4 wheels — 2 of them brake casters — which makes it the only FunXplore catio you can genuinely move in and out of the house by yourself. This is the right choice if you want to bring the catio inside during severe weather or if your outdoor space changes seasonally. The removable middle floor gives you two modes: keep it in for a 2–6 cat configuration with distinct levels, remove it for open floor-to-ceiling climbing space. The window-facing sliding door connects to an indoor window or cat flap the same way as the larger walk-in models.

Getting an insulated cat shelter through a genuine winter — temperatures regularly in the 20s°F, wet ground, wind — requires more than buying the right box. Placement, bedding, exit orientation, and heating pad decisions all affect whether a feral cat actually uses the shelter and stays warm inside it. Here's what actually works, based on what verified buyers report and what FunXplore's construction specs make possible.

Where to Position the Shelter

The single biggest warmth factor is wind exposure. A shelter sitting broadside to a prevailing northwest wind loses heat through the walls regardless of insulation rating. Position the shelter so its back faces the dominant wind direction — not a door opening. For the PD-1002 (34.5"D × 21.7"W), the two escape doors are on opposite sides; one should face away from the wind and serve as the cat's primary entry, while the other faces a less exposed direction as the emergency exit route.

Elevate if you can. The PD-1002 and PD-1001WA both have elevated feet, which lifts the floor panel off wet or frozen ground. That matters: even 0.47-inch fir wood conducts cold from a frozen concrete surface. On a wooden deck or porch — which many feral cat caretakers use — the shelter sits well clear of the worst of it. On bare ground in a yard, adding a thin piece of rubber mat or scrap lumber under the feet adds another buffer.

If you're placing the shelter against a building wall, go for the south-facing side if possible. A shelter backed against a north-facing wall in a shaded area gets significantly less solar warming during the day, which makes the foam insulation work harder at night.

What to Put Inside

Straw — not hay, not blankets. This is something the feral cat community is consistent about. Straw is hollow-stemmed and traps air for insulation without absorbing moisture the way blankets and fleece do. A wet blanket inside an insulated shelter is colder than no bedding at all. Fill the floor of the PD-1002 (4.1 ft² interior) about 3–4 inches deep with loose straw, and a cat will burrow into it and create a body-heat pocket that the 6-side foam walls hold remarkably well.

One buyer in Minnesota reported their porch cat's shelter maintaining noticeably warmer interior temps than outdoor air even when temps dropped into the single digits. That's plausible: the 0.6-inch styrofoam sandwiched inside the 0.47-inch fir panels creates a sealed thermal envelope on all 6 sides — including the floor and ceiling — which prevents the convective heat loss that single-wall shelters can't stop.

Dual Exit Orientation for Feral Cats

Both the PD-1002 and PD-1001WA have 2 access doors. For feral cats, this isn't about convenience — it's about whether the cat feels safe enough to use the shelter at all. Cats with only one exit are vulnerable inside a box. A feral cat that senses something approaching from the front door has no way out.

Orient the primary entry door away from the most common approach path in your yard — typically away from where you or neighbors walk, or where other animals approach. In urban and suburban settings with raccoons active at night, position the secondary exit so a cat can bolt in the opposite direction from the entry point. The PVC door strips on the PD-1001 model's entry can be a barrier for very shy ferals at first — some caretakers tie them back or remove them temporarily while the cat gets comfortable, then reattach them once the cat accepts the shelter.

Heating Pad Compatibility

Several verified buyers have drilled small holes in the corner or base of FunXplore shelters to run a heating pad cord through, then siliconed around the hole to seal it. This works, and buyers report success with it. A few things to know before doing it:

• Use only a pad rated for outdoor or pet use with an automatic low-temperature shutoff — never a standard electric heating pad designed for humans.
• The foam insulation in the PD-1002 and PD-1001WA is sealed within the wood panels — you won't hit it by drilling a small-diameter hole through the corner base, but drill into a corner, not a center panel, to avoid the foam layer.
• The shelter's sealed foam construction means heat from a pad stays inside more effectively than in an uninsulated box — a low-wattage (5–7 watt) pad is typically sufficient. Higher wattage in a well-insulated space can overheat a small cat in very cold but not extreme weather.
• The removable floor on both models makes it straightforward to place a flat pad directly on the floor panel, which also makes periodic replacement easy without disassembly.

Maintenance Through Winter

Check straw monthly during winter. Wet straw compacts and loses its insulating properties — if it smells musty or feels matted, replace it. The hinged roof on both insulated models lifts fully open for top-down access, making a bedding swap a 5-minute task. The asphalt shingle roof on these models sheds rain without additional treatment, but if the shelter sits in direct sun for long periods, an annual coat of exterior wood sealant on the outer panels extends the life of the fir significantly — particularly on south-facing surfaces.
