How many litter boxes per cat?

When we had two cats.. we just had one big litter box. Didn't seem to be any problems. We did clean it daily though...

I had 1 for 3 well-behaved cats who all get along (that's the key!). Now that I have 4 cats, I had to add another. I don't want them all over the house so they're both in the laundry room. Both get scooped twice a day without fail.

One cat. One box. Scooped daily.

Same here - 3 cats, one box. But it is scooped at least 1x per day. They were all shelter cats, so they have always been used to sharing a box. We have an average, one story house. If we had 2 stories, I would probably add another box for 1 per floor.

We kind of have one box per cat here, but not purposefully.

My cat only lives in our room/the backyard so she has a box to herself. The other 3 have 3 boxes in different rooms. Two in different areas of open living spaces and one in another bedroom because we keep doors closed.

When we had two littermates, one box, cleaned daily was fine. When we've had cats that weren't littermates, we had a box per cat. We've never had more than one box per cat and have never had problems.

We have 2 cats, 2 litter boxes, though they only use one. I feel like if I took the one away, even though they rarely use it, they would be little assholes and pee in the spot it was.

My two girls share this litter box MODKAT. I’m a condo dweller so finding a spot for one in my laundry room was challenging enough, it is small. In fact, I’ve almost always had 2 cats rather than 1, and have never had multiple boxes. One of my cats intensely dislikes the other (the other one still tries very carefully, but after over 2 years I don’t think she’ll ever break through the other one’s barrier) so I’m actually a little surprised that they’re ok sharing.

ETA: I think part of the key for sharing is to clean it regularly. I clean it every morning while my coffee brews. If I’m in there during the rest of the day, I’ll automatically clean it again. Having a Litter Genie right next to the box for the past 10 years has made scooping so much easier!

I have two cats and two litter boxes ... I'm a very experienced cat owner and this is just the magic number ... when my mum's cat is visiting I bring out a third    

Four boxes, two cats.

Scooped every day.

six cats (4 seniors, 2 kittens) - 4 BIG, 1 little litter boxes

there is a BIG litter box in both upstairs bathrooms. Only Tabby and occasionally Mini use it. The kittens only go upstairs following me so aren't up there enough and Midnight can't manage the stairs and LF won't.

There are two more BIG litter boxes in the utility room - all of them except Tabby use them. One is primarily pee and the other primarily poop.

When we got the kittens, they were confined to our room so we added a small litterbox (it barely fits) in our bathroom and it's still there even though kittens have the run of the house now. It's not big enough for the older cats to use.

We’ve always had one box per cat, but the cats were always adopted at different times. We adopted bonded brothers this year and they share a box. That box is on the 2nd floor (cat floor). The dogs rule the ground floor. We have kept the cats out of the basement, which used to be where the litter boxes were for our previous cats. The new cats were using the hole where our water meter is for a litter box. I guess they liked the dirt more than the litter. It was so horrible. We had to poor a shitload of urine eliminator in that hole before we killed the ammonia smell.

2 cat, 2 boxes and he mainly uses the backyard
