Why should the dogs have all the fun? While many kitties don't want to walk on a leash [1], fresh air can do them good . . . even if it's just a walk to the vet. The KittyWalk Pet Stroller — Double Decker ($249.99) [2] is like a duplex carrier for cats featuring durable nylon netting and water resistant fabric holding two 18-pound pets on each "floor." My fave feature of this stroller is that it can be used as a separate hand-held carrier or as a wagon to tote other heavy goods like . . . hmm . . . laundry. Now, I know many of you have kitties that don't even want to get into any carrier [3], so I'm worried you get it home and be left using it to cart around groceries instead – what do you think?
