Many households have issues with allergens and you don't want your cat tree to contribute to the problem. To address this issue, Cloud 9 Cat Trees offers a number of products available constructed entirely of wood (no carpeting) giving them "near" hypoallergenic qualities. Not absolutely hypoallergenic but reasonably close.

The base, trunk/posts and base of the tree models are of all wood construction with a clear water-based polyurethane for a waterproof and durable finish. These trees can even be used outdoors.

For those who want the cat tree to also serve as a scratch post, the trees have a sisal rope option for the trunks/posts.  These models are not as hypoallergenic as the All Wood trees but are an attractive addition to many home decors.

In addition, both the Single Wave and Double Wave shelves are available in a wood finish.

The following All Wood Cat Trees are available:

• All Wood Stratus Tree - with 1 small, 1 medium and 3 large Cedar Flats
• All Wood Classic 1-Tier Tree - with a large Cedar Flat.
• All Wood Classic 2-Tier Tree - available with 2 medium or a medium and a large Cedar Flats.
• All Wood Classic 3-Tier Tree - available in a mix of medium and large Cedar Flats with an optional Inline posts and base.
• All Wood Classic 4-Tier Tree - also available in a mix of medium and large Cedar Flats with an optional Inline posts and base

The only other options available for these All Wood Trees are a light, medium or dark walnut stain for the base, sisal rope upgrade and, for some models, a Tall version is available. Please see the individual product pages for more details.
