How often do you clean your cat's litter box?

Daily. I use two kitty boxes and a large mesh ravioli strainer. I just pour one pan through the strainer into the fresh pan, and throw the old pan into the shower for rinsing. I buy the clumping litter in bulk at the pet supply: 30 lb. for $10.

It's kind of random, my wife does it about as often as I do.

No cat.

That comment would be fun out of context.

Isn't it interesting that the default context for any statement seems to be sexual. ...like adding "in bed" at the end of a fortune (from a cookie).

I had a cousin who turned every single thing a person said into a sexual connotation. Suppose my imagined context was 'making presumptions'?
Alas, it wasn't. But I'll have to try the cookie trick.

I have an automatic litter box all you have to do is dump the waste container that it gets scooped into. It is a great litter box low maintenance and low odor.

I scoop it out about twice a week, and completely change the litter every two or three weeks.

not often enough

When I had a cat I cleaned out the clumps daily. Now I don't have a cat, and litter boxes are why.

no cat, but I change my hamsters cage about once a month

I don't own a cat, but I want one. *sigh* I have to settle for a stuffed animal cat named Felix.

OK, OK, I'll clean the litterbox already!

My cat does not need a litter tray, she's well trained to go outside.

Until a few months ago, I had to settle for a stuffed siberian tiger named Fergus. But now I have the lightening brothers, Volt and Schism. They make quite a difference in my life.

The lightening Brothers?

I don't have a cat.

scoop once a day and change it once a week.

I have a 2 ferrets which use the litter box. Usually once a day, once every 2 days if i'm tired

My gray tabby cats. With a collective nickname you could expect from a metaphysician. Their kitty collar bells spread scintillating energy and they run through the yard & up the stairs fast as lightning.

Oh, they sound cute! I wish I had a cat.

I suppose twice per week -- I clean both of them once a week at the same time (two cats), but there's two. Does this equal twice?

How many cats?

I think she said 'two'. In fact I think she said 'two' twice. And she said 'twice' in 'both' sentences.
Question is does 'clean both' refer to litter boxes, or less likely - '(two cats)'. My cats share food bowls and a litter box. I wonder...

...Do your cats use each others litter box? Do they use them at the same time? Do they use them at the same time as you? (use your toilet, not their litter boxes.) Actually that's a valid question too. My cats have the annoying habit of choosing to use their box just as I am about to clean it. I think it's a conscious decision to have a cleaner litter box. They're pretty bright cats. (even if they seem oblivious of the concept 'move it!')

Yeah, I was wondering if they had their own litter boxes... because my cats share one too.

My cats like to crap as soon as the box is clean.. I guess they like to use it fresh.. The stand and watch me clean it.. and as soon as I'm done, they jump in.

My cats will do that too. Perhaps they're just wandering minstrel space cadets with ADD and my movements towards cleaning the cat box remind them to handle their own movements.

No kidding -- yours too? Mine do the same! It's as if they sense the changing of the litter; they're always right there to witness and poop. What a pain in the ass.
I've not seen if they use "each other's" -- I simply keep two boxes to reduce the frequency of cleaning! I doubt that they stick to one, though that's a good question. What part does scent play?

I have the answer. It lies in territory marking. Just like cats in the wild will piss and crap in certain areas(even the big cats do this)to outline their territory, house cats will spray and poop as a means of staking a claim on areas...Your cats are saying : "Hey! That cat box is mine and I have to make it smell like me again since you washed all the "me" smell away and some other outside cat might walk by and decide to take it over if they don't smell "me" in it!"

Cats have scent glands in their cheeks too. Thef mark you as territory. Mountais Lion poop is usuful for keeping deer out of your garden. And me, I'd stay away if I smelled Twisty's doo-doo, or even her monkey's doo-doo..

My monkeee throws its doo doo at yoo yoo...

?! I hope to not be smelling too much excrement.

but eventually he get's into his job; the zoo visitors haven't a clue the real bobo the ape has died. He starts throwing doo doo & banana peels at his admirers, and using the gymnast skills they hired him for. He get's too exuberant though, and swings over the wall to find himself face to face with a lion. "Help, help, he screams", and the lion whispers "Shut up, you want us to all lose our jobs"? - one of my favorite sermons.

What's that from?

Heard it as a kid, liked it cause no one gets hurt. Figured out 15 years later what a great metaphor it was.

Never. My cat uses the great outdoors as his/her litter box.
