The Cat Trees are flourishing just a block up from where Eagle Rock blvd ends Fletcher (technically that is Ave 36). In a garage on 3737 Eagle Rock, with the sign painted on the outside that says "Carpet Center" resides a Cat Tree Nursery with brilliant designs.
These guys run from $65.00 to over $200.00, with hideouts, scratching posts, and all sorts of perches upholstered in a variety of piles and shags. They also do custom work. I spoke with Oscar (below) as he contemplats his next design.
