AIVITUVIN Insulated Outdoor Cat House: Listing Review

As an Amazon Associate we earn from qualifying purchases. Details

The AIVITUVIN outdoor insulated cat house listing is for one product: the AIVITUVIN Cat House Outdoor Insulated Feral Kitty Shelter with Liner, in grey with the liner. It is a wooden shelter with a removable insulated liner, an asphalt roof, PVC door flaps and a large opening roof. This guide covers what the listing says about the liner, the build, the inside space and assembly, and it notes the claims the listing does not back with numbers. Every claim comes from the listing or from the sources at the end.

Quick answer

• The listing describes an insulated liner made of high density sponge and fabric with a PVC coating, and the liner can be removed and machine washed.
• The shelter is made of fir wood with waterproof paint, an asphalt roof and PVC door flaps.
• The listing gives an inner space of 23.6 by 20.9 by 18.3 inches and says it fits one or two cats.
• The product dimensions are 20.9 by 23.6 by 18.3 inches, and the weight is 20.05 pounds.
• The listing gives no temperature rating and no weather-resistance test result.

What the listing describes

The title reads “AIVITUVIN Cat House Outdoor Insulated Feral Kitty Shelter with Liner Keep Warm for Winter, Waterproof Cat House for Cats, Large Opening Roof.” The product details give the material as fir wood, the color as grey, the style as classic and the item model number as AIR12. The first-available date is July 18, 2019, and the manufacturer is Aivituvin.

The bullet points make five claims. The insulated liner is made of high density sponge and fabric with a PVC coating, and the listing says it can be removed for machine washing. The fir wood has a waterproof paint, and the roof is asphalt with PVC door flaps. The inner space is listed as fitting one or two cats and other small animals. The floor can be moved, the roof opens wide, and three vent holes provide air movement. The listing says assembly takes about 15 minutes with a screwdriver.

The variant list shows several sizes and a heater option. This guide covers only the grey version with the liner. The page read for this guide also showed a notice that the item cannot be shipped to the delivery location selected in that session, so check the shipping message before ordering.

Liner, roof and door

The liner is the main upgrade the listing describes. The bullet calls it an insulation liner built for warmth, and the title says it is meant to keep the shelter warm in winter. The listing gives no measured insulation value and no temperature range, so the liner’s effect cannot be quantified from the page.

The asphalt roof and PVC door flaps are described as weather protection. The listing says the shelter is waterproof, but it gives no rain test result. The flaps help block wind and rain, according to the listing’s own design description, and the roof opens for cleaning.

Bedding inside the shelter matters as much as the liner. Alley Cat Allies advises loosely packing the straw in the shelter to the quarter or halfway point. It recommends straw over hay for outdoor cat shelters, because straw repels moisture and hay becomes a soggy mess. The same organization warns that in winter a wet bed can be dangerous and can make cats more likely to get sick. Avoid fabric blankets or towels inside the shelter, because they absorb moisture and can make the interior colder.

Size and fit

The listing says the shelter fits one or two cats and other small animals. The inner space of 23.6 by 20.9 by 18.3 inches is the figure to measure against a cat’s length when it lies down. A larger cat may not turn around in a shelter this size, so measure the cat before choosing.

The listed weight of 20.05 pounds is for the shelter as shipped. Choose a level spot, and keep the entrance clear of leaves and snow. Alley Cat Allies advises removing snow from all shelter entrances and exits, because it is important to keep cats from getting snowed in.

Dimensions to check

The page gives two sets of dimensions for the same model, and they do not match. The table below sets them side by side, so the buyer can see which figure to measure against.

Source on the listing	Figure given	Use it for
Product details, product dimensions	20.9 x 23.6 x 18.3 inches	Overall footprint as the listing states it
Variant table, insulated liner row	20.3 x 16.5 x 16.9 inches	Overall size of that row, as the variant table states it
Bullet point, inner space	23.6 x 20.9 x 18.3 inches	Inside space for a cat

The listing does not explain the gap between the first two rows. A buyer with a fixed spot, such as a porch corner or a fence line, should measure the spot and then ask the seller which figure applies before ordering.

Checklist before ordering

• Measure the spot where the shelter will sit, and leave room for the door to open.
• Measure the cat from nose to base of tail, then check the inner space in the table above.
• Confirm that the shipping message at checkout accepts your delivery address.
• Decide on bedding before winter. The listing does not name a bedding, so the straw guidance below applies.

Assembly

The listing says assembly takes about 15 minutes with a screwdriver and that the screw holes are aligned. The bullet says the design is easy to assemble, and the listing does not say how many people the job needs or whether the instructions include diagrams. A buyer should still check the box contents and the hardware before starting, and should confirm the roof and door sit square before the first use.

How we chose
