Awesome Lighthouse cat, kitten play house; this is the 1st of 3 videos showing the building process from plans found on Etsy: https://etsy.me/3atLHNg
Its a cat tree, a scratching post, a house, a 7' tall lookout tower, yet it has a small 2' square foot print to fit almost anywhere. And, unlike typical cat trees, it adds beauty to décor
Made from cardboard, it is easy to cut and assemble with just a utility knife and a glue gun all you need are the plans and patterns found on Etsy.

This 1st video shows the steps of making the inner Stairwell tower from the patterns found on Etsy.

Plans are found on:
Etsy Playhouse4pets shop.
