As one of its daily deals, That Daily Deal offers the Vesper V-Line Elevated Cat Cave Cube with Scratching Pad for $59.99 with free shipping. That's $60 off and the lowest price we could find. It measures 20.5" x 20.5" x 24.8" features a replaceable sisal scratching pad. Deal ends January 5.
Note: It ships in Tan or Dark Brown, chosen at random.
June brings some big deals and sales, but you're better off postponing certain purchases.
