Ah, the pitter patter of four-legged feet as they whip through your living room at overclocked speeds or uproot your prize gladiolas with manic fervor. But Snookiepuss and Mrs. Fluffypants are practically family, right? So why should they settle for anything less than top drawer when their health and wellbeing are at stake? Throw the planet a bone while you’re at it; check out the best of TreeHugger for advice on how to green your pet and reduce your pets’ carbon paw prints — without making your wallet roll over and play dead.

) For pet playthings, look no further than a scratching post made from recycled cardboard [www.treehugger.com] and toys made from recycled materials [www.treehugger.com] and filled with organic catnip.
) To help your pets relax in green style, check out this cardboard lounger [www.treehugger.com] and these slightly more substantial wooden pieces [www.treehugger.com].
) Swheat Scoop [www.treehugger.com] wheat-based cat litter is made without clays and chemicals, and is fragrance-free and biodegradable. It’s even flushable.
) If you’re out and about when your pet does the deed, we like Oops, I Pooped [www.treehugger.com], the clever biodegradable pet-waste bags.

) Not to be weird about it, but we’ve really had to stand drop-jawed about the awesome power of poo [www.treehugger.com], as with San Francisco’s pilot project (the nation’s first) to turn dog poo into clean fuel [www.treehugger.com] by way of methane digesters.
) Dogs and cats aren’t the only TreeHugging pets, though; a Seattle Councilman wants to allow keeping goats as pets in the city [www.treehugger.com], to be used as petroleum-free lawnmowers and weed-wackers.
) While we’re at it, why not have a chicken or two as a pet [www.treehugger.com]?
) If you’ve got a hamster (or other small caged rodent) be sure it earns its keep by helping you charge your cell phone [www.treehugger.com].

) In the same vein, teach your dog to mush with the dog-powered scooter [www.treehugger.com] for some fun, emissions-free transportation.
) When your pooch or other pet it all worn out, put ‘em to bed on a Hemcore bed [www.treehugger.com], animal bedding made from the inner core the hemp-plant stem.
) If mushing isn’t your dogs’ favorite thing, get some eco-friendly doggie travel gear [www.treehugger.com] from Planet Dog so they can travel with you in green style.

We noted yesterday that design — that is, products like furniture and architecture — that packs flat makes a lot of sense, and is generally a better way to do things. It requires fewer resources to manufacture and produce, is more space-efficient for shipping and allows for quick ‘n easy modularity, for when you’re on the go. If your furniture should fail you, and break, the modular pieces also make it easy to replace just the one broken part, rather than the whole piece. Here are some of our favorite examples of furniture that packs flat.

1) Our Top 5 picks for flat-pack [www.treehugger.com] include a London-based company [www.treehugger.com] who manufacture everything to order (cutting out the need to ship and store furniture before it’s bought), this groovy garden chair [www.treehugger.com] made from one sheet of sustainable plywood, and a “heavy metal” chair [www.treehugger.com] that’s created from a single sheet of perforated (and bent) steel.
2) Designer d.e Sellers came up with the “Emergency Stool” [www.treehugger.com] (pictured above) a single, mobile sheet of plywood (that would make a pretty interesting wall-hanging) but comes apart to create a handy bench. The laser-etched, international instructions (see ‘em on the big piece in the middle) make it a “snap” to put together, as it requires no tools or fasteners.
3) The Knockdown Bookcase [www.treehugger.com] is a great modular option that does the job without glue, hardware or even an instruction manual. Each piece is identical and just slips together to create a modern, modular bookshelf, and the design variations are limited only to what your imagination can dream up.
4) Factum furniture [www.treehugger.com] is sustainable, foldable, and mailable — that’s right, it’s just like getting a package through the mail. It is produced using recycled cardboard and printed with a variety of designs. The patterns are diverse and fun, from floral to the periodic table to the London Tube system.
5) In the same vein, the Papton chair [www.treehugger.com] from Berlin-based Fuchs + Funke goes from flat panels to functional chair in a couple quick fold & fit moves. The structural, geometric result is a real lightweight, weighing it at just two kilograms.

6) German designer Nils Frederking has bowled us over with his folding chair and table [www.treehugger.com] that seem to defy ordinary furniture physics with their deft foldability. Words don’t do the designs justice; you have to see the video [www.treehugger.com] to get the full effect.
7) The designers at Because We Can like to have fun with their work, which is easy to see in the Tree Stump Coffee Table [www.treehugger.com]. Aside from being flat-packable, the table uses sustainable materials and CNC (computer numerically controlled) routing to create the design with a minimum of offcuts and wasted material.
Combining design and engineering experience that includes Indy 500 winning racecars, composite aircraft, consumer products, and industrial equipment, Scott Bennett’s Housefish now specializes in modern, contemporary furniture. Their newest product, called Key, starts with Forest Stewardship Council (FSC) certified maple veneer plywood, which gets a low-VOC finish before flat-packing for shipping.
9) Davidgraas has integrated brilliant packaging design into his flat-pack furniture: the package is the product, as the zero-waste design uses everything in the package to create the product.
10) Lastly, just for fun, there’s the Grass Chair (below), a flat-packing, true do-it-yourself project that allows you to grow your own furniture; you may have to see it to believe it [www.treehugger.com].
