Have to share this for all you wine-loving cat owners out there: My co-worker Arnaud shows off his DIY solution of his cat's litterbox using a wooden wine crate...
One side is hinged for easy scooping access, and lined with plastic to keep the kitty litter from leaking through any cracks in the wood.
Thanks for sharing Arnaud!

White Enamel Four-P...
This is fantastic, unless you have a kitty that likes to scratch and is constantly ripping the lining. :( Very chic, none-the-less!

It is a great idea in theory, however, all cats (except those who have been declawed) like to scratch around their litterboxes, which means that unless you have a steel liner, there are gonna be leaks, and the odor will be nearly impossible to remove from the wood. And then there's the problem of rotting wood. Plus, the cover provides no ventilation, so odors will be trapped and the ripening process will accelerate, which might encourage kitty to find his or her own alternative that might just be your bed.
Sorry to be so negative, but sometimes reality does stink.
I agree with the others. Why not find a small litter tray to put inside rather than using a plastic bag?
my cousin built me a little box and he covered the inside with shower board (pretty cheap at home depot) and then just sealed the corners. that would work great for this box too. i love it! so much more appealing than my white painted box.
i would use a litter box inside though, just so its more sanitary and easier to clean. i bought a large plastic storage container (one for under the bed). all the litter boxes they sell at stores are so small and dont really give cats much room for moving around.
and just to throw it in, feline pine is the best cat litter i've found. it's so much better smelling than clay and it really works. it's also healthier for the cats. i have six cats, so i tell people if i say it works, trust me!
I love this idea and with some work to protect the insides from kitty pee (one of my little guys "aims high") it would be perfect. As far as litter goes, I'm using a litter with the Disney "Aristocrats" all over the packaging and it works really well to cut down on odor.
I'll prolly make it as a kitty home cos its more chic-looking than a stinky ol' wine-pee box!
I like it. It's SO much better-looking than the plastic stuff out there.
That said, I do see the point being made re tearing, odor, leakage, etc. The steel liner suggestion was apt, but perhaps aluminum or strong rigid plastic would be other (and cheaper?) options. Any of these, supplemented by a easily disposable thin plastic liner on the bottom, should do the trick.
I might even line the top portion, to avoid the possibility of odor permeating the wood.
Also seconding savyvegan's endorsement of Feline Pine litter.
Congratulations for thinking outside the box! (sorry)
I think that this is a great idea. It could maybe use a few adjustments, but overall it's awesome. I use wine crates for my rabbit litter boxes. I just put a rubbermaid dish tub inside to protect the wood and they look pretty nice.
beautiful!! i would love this for my kitty... if i can make one myself.
I love the idea, but my last cat used to wipe her paws on the opening of her cat litter box to get off any that had stuck to her. Easy to wash off plastic, but probably not so much rough wood. Maybe several coats of polyurethane would help the wine crates?
This will be a perfect hidey house for my rabbits!
cool.
agree that it might be easier for you to maintain if you put a plastic litter box/bin something in there.
Some sand/litter/stuff will get kicked out into your boxes, but will be easier to clean than the liner in the picture.
Clean = cool.
Love your idea!
A film plastic liner will be ripped to shreds (just ask my furballs, Siska and Moose). Use a plastic litter pan inside. Also, put wedges of wood dough in the bottom corners; they'll make cleaning the corners much easier (moosh them in, smooth them out). Give the interior a couple coats of varnish to prevent odors from staying (let the finish dry for a week or so before using). Give the outside a coat or two also; it'll prevent the wood from warping.
Finally, the Box needs a good vintage name, like Chateau du Chat, with a little crescent moon over the opening!
