Why should the dogs have all the fun? While many kitties don't want to walk on a leash, fresh air can do them good . . . even if it's just a walk to the vet. The KittyWalk Pet Stroller — Double Decker ($249.99) 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, so I'm worried you get it home and be left using it to cart around groceries instead – what do you think?
