Introducing: Akemi Tanaka's Curve Wall Mounted Pet Bed.
It holds up to 45 pounds (meaning it works for small dogs, too), comes in a variety of wood finishes and fabric options, and is $199 at Supermarket.
Seriously, I don't know how our cats have survived without this.
And speaking of pets, have you all seen this video? Apologies if it's old news, but I just discovered it yesterday and think it's absolutely amazing. I mean, really -- who needs kids when you can train your dog to do this?
