Stop sleeping in litter.

keep them off the bed.

Is the AC the only thing that's changed in her environment? (No new pets? New home? New furniture?) Make sure she's not sick. Sometimes, when cats are sick or angry at you, they do stuff like that. If it's only the one cat, it's worth a phone call to your vet - as long she's eating and sleeping and playing the same and nothing else has changed.

Well has there been a great move or something new that has been brought to the place since before she started back up peeing? If so that may be the reason why she is peeing again. If that is the case it may just take awhile for her to get use to the new thing or things, and once she is use to it she should go back to being her normal self. If nothing new has happened or brought in then it might be something medical and I would go have her checked out buy your vet.

Give her to the humane society.

First off does your cat spray for pee? Many cats use urine to mark their territory. Instead of squatting and urinating in a puddle, the cat will raise its tail and squirt the urine backward toward the object it is trying to mark. if your cat is urnating. Be sure to thoroughly clean soiled areas of carpet with a commercial product designed for that purpose (ask at your pet store). If the scent is not eliminated, the cat may return to the scene of the crime and repeat the offense. A clean, strategically placed cat box should prevent this problem. Some cats require privacy, so a box placed in a high-traffic area can lead to trouble.

Get her fixed, she in heat more then like-ly and she is marking you as hers. To worn the other cat's to stay away. My cat use to do that 2. I had him fixed and he stopped. It could also be her way of telling you the cat box is to dirty for her and you need to clean it. Some cats will not go in a cat box if they think it isn't clean.

Take her to the vet to be checked for a bladder infection - my cat did this out of the blue and he was VERY sick - I would never have known if I hadn't taken him in.

Ok, the stop sleeping in litter advise is funny. But really, cats tend to pee where they shouldn't when they feel unsafe/unloved or sick. You have 5 cats, she probably feels left out some how. But before you assume it's behavioral, try 1)Changing the litter more often- use the throw away kind rather than scoop and change the box every 3-6 months to keep the smell down; sometimes it smells too dirty and cats go elsewhere- wierd I know. 2) Vets can tell you if it's an infection and easy to fix, but only if you go soon. Good luck!

if u want the cat to stop u put the cat outside to run around or put it in a cage outside and then it should stop if you dont show it the litter pan and lock it in the cat room for while

She may be holding something against you. Got a new significant other? Maybe you're not giving her the same kind of attention you use to??

First, get a vet exam of your cat. My cat did that, too, and I was so busy, I really didn't make the necessary checks to rule out health problems. To my dismay, I finally had her examined, only to find out that she had diabetes. The sad fact is, she was too old and frail by the time I found this out, that the treatments didn't work. I honestly believed her diabetes was to blame for her peeing on the bed. Please take her in and make sure there aren't any physical probems with her. Multiple cats can be a problem for some cats, as well. Do check a vet, though. That should be your first step. Good luck.

My boyfriend had this exact problem. He took her to the vet and found out she suffered from seperation anxiety (they put her on Prozac--no kidding), then when she still kept doing it he resorted to laying hard sheets of plastic (you can get those from a hardware store) over his bed when he was not using it. That detered her from peeing on the bed, but then she started peeing on the floor too, sadly he had to find a new home for her where she would be an outside cat only. Hopefully your's is a treatable medical problem, but try the plastic until you can get her to the vet to figure out what's wrong. Good luck!

first is she spayed? if not then se needs to be. i have a calico that went into heat before i could get her fixed and she freaked out and she actually jumped on me in the middle of the night and peed on me! she was confused and didn't know what was going on and she decided she needed her moms help.(i wish she could have found a better way.) anyway, i have the same problem with her every now and then and she will pee on my bed. you will have to completely strip the bed and thoroughly wash everything. turn the mattress over if it went through. get a good waterproof mattress pad incase this happens again(i finally got smart and got one, better safe than sorry. anyway i cant control this when i'm away to i have another water proof mattress pad the kind that just lays on top on the mattress and doesn't tuck under. i lay this over the top of the linens so if it happens again atleast my lines are saved and i onlu have one thing to wash and not a whole bed load. you can also keep the cats out of your bedroom when you are not home, but they are fast and can pee right infront of you if they are so inclined. try adding a couple of more litter boxes. i have a lidless pan under my bed too. i keep it clean so there is no smell. you might also want to have her checked to rule out a urinary infection.

Maybe she's trying to tell you... "clean my litter box!!!!!"
