Without spending a ton of time looking at the site, a few little things pop out at me:

• The fact that the navigation menu lists “catalog” but when you click on it, you only have one item (it’s not really a “catalog” then).
• You have filter and sort functions on a page with only one item for sale.
• There is the option to “add to cart” but at the bottom it says you are taking pre-orders, so which one is it? If it’s only available for pre-order, I feel like the button should say “pre-order now” and have the expected delivery time listed directly underneath the button.
• The black background in the photos is just bad, but then again, the photos in general are pretty bad as well. And is there only one screw holding the thing in place?
• I feel like you need to clarify how this could work on any cat tree (if it even can) - for what you are trying to charge, that seems like an obvious thing that people would want to know.

There’s certainly more issues that that, but I don’t want to be to harsh in one go.
