Do you know for sure which cat it is? Or do you suspect both?

The first thing I'd do is take the cat to the vet for a check-up. There might be something medically wrong.

Then look at the litter box carefully. The only time my cat peed on my bed was when I let the level of litter in the box get too low. I was going to change out the entire box the following day, so I didn't add new litter in. And she let me know that was unacceptable.

Could one cat be intimidating the other from getting into the litter box? I had this problem once. It wasn't a matter of the one cat getting in the other cat's way or hissing at her or physically blocking her from the box. She would just lounge in the general area of the bathroom door (the box was in the bathroom) and the other cat was afraid to pass her by. They got along great otherwise. Adding a litter box at the other end of the apartment solved that problem--the "mean" cat couldn't block all the boxes at once.

If you have two cats sharing one litter box, you might need to clean it out more often, say two or three times a day instead of just once. Cats can be finicky.

You could try using the "Cat Attract" litter.

Sudden inappropriate eliminating and spotting are THE signs of a bladder infection. Please take her to the vet.

what elly_nj said...to the vet

First, as others said, make a the vet appt. The fact she's also going on the floor in several places points to a urinary infection. Second, you need to closely watch the interaction of both cats to determine if one is being dominate over the other.
Add another litter box so each cat has their own, and locate them in opposite sides of the room.

Have the cats been spayed? Also, what is your mood when you're around the cats? If you're agitated from the cat's urinary problems then this will just add to the cat's stress level. If she's already ill, stress is the last thing she needs.
Do they have plenty of things to play with and do they have a window to look out for a change of scenery? I can see where they may get a little stir crazy being kept in a bedroom, but I think there's something going on, either medically or environmentally, for your cat to start this behavior.

Until you have her checked out and make some changes, I'd leave the bed covered with the plastic cover and place all your bedding outside the room when you're gone. Make sure you're treating the bedding with Nature's Miracle since soap and water won't remove the odor.....maybe it does for your nose, but she'll still be able to smell it.

I had totally forgotten about this, but I had the exact same problem with a cat many, many years ago. Had a litter box in the room and he insisted on peeing on the bed. It turns out that he did not like the litter in the box. I solved the problem be using an unscented litter, and adding some dirt (yes, plain old dirt from the yard) in the box. Once I moved out of an apartment, and he had access to the outside, he never used a litter box again. I second the vet visit to rule out problems, try a couple of boxes with different litter, and what the heck, try some dirt in an unscented litter. Any possibility they could get outside a bit, even if on a lead?

I know this post is old, but I thought I'd add a tip, for any one new who finds this during their search.

The general rule of thumb is 2 litter boxes PER CAT, I know that is not feasible in all homes, I have 3 cats and can only do 3 litter boxes, I personally do not have room 6 litter boxes they'd be sitting side by side - if I did and that just doesn't seem like it would work as it's supposed to.

The reason for this general rule of thumb, is that cats supposedly don't like to potty where other cats go potty!, I can't say that I believe that 100% as my 3 cats use only 2 of the 3 boxes, and they have their "favorite" all boxes have the same litter, and basically the same size the one they don't use is actually the biggest.. But if 2 or all 3 have to go at the same time instead of each one going to their own box, they actually will "wait in line"! for the one using it to get out!.

Also cats are extremely finicky when it comes to their litter box, they want a spotless, odorless box or they'll refuse to use it (not all cats, some just don't care, but most do). I have 1 when the boxes are not spotless and odorless of any of their own scents, she will not use it, she will go on the bed, the floor, clothes left on the floor, the couch, any where but any box. So we make sure to clean the box at least 4 times a day, with a complete dumping out into the outside trash once a week, and after we dump it all out, we scrub it clean with dish soap and water, dry it, then I put a thin layer of baking soda (even if my litter already contains it), then the litter.

I also have a male cat who is very picky about the brand/type of litter we use, if it is not to his liking he will kick it all out and just go in the box after he empties all the litter - much better than going on our furniture, but to be honest he makes a bigger mess for me to clean up, I'd rather wash bed clothes or a fake leather futon couch/bed off than to always sweep up cat litter.

And I agree with getting them outside time - they may be doing it out of being bored they're locked in a room (think of it like this, that room is their jail cell, would you want to be locked in a jail cell 24/7 and only get out 1 time a week if that for ''recreation'' ). I have built a fully enclosed cat kennel for my cats I used an old metal dog kennel and added wire to the top as well, They have 2 decent sized logs in it from a cut down tree to sit on and scratch on, they have one long branch that had broken off my tree in there at an angle, they've got a large cooler that has a hole cut into it and it's full of old clothes, straw, and old foam (from outside furniture), this is their "house" they go in when it's raining or gets a bit cold (I have 1 male who prefers to be outside he's happier outside than inside) they also lay on top of it, they have their own cat nip growing in there as well. They love this kennel! Plus they get fresh air, and the vitamins they desperately need from the sun they are unable to get from being cooped up in a house.

No cat should ever be strictly an indoor cat - I'm not saying allow your cats to roam your town (if you live in the country and there is not a high chance of them being hit - and you know they'll come home every night - then feel free I did it when I lived out in the country) but every cat needs to be outside for a few hours every day, rather its in an enclosed kennel they can't escape, or wearing a harness and on a lead they can't escape from. But they need outside time! Also they need to spend time with their entire family, cats are social animals, being jailed up all the time is not good for them mentally , physically, or on their over all internal health
