Hope things are getting better!!. As others have written, there is a medical or emotional reason for the peeing outside of litter box. Cats normally are fastidiously clean - cleaner indeed than most humans! So a thorough med exam would be very informative - a urinary infection, as has been said, can easily cause this problem though it sounds like that may not be the case since she's using the box in the bathroom without any troubles. Age can also cause some incontinence as with humans. With lots of cats in residence, extra litter boxes help. Mine won't even consider using one that has any soiling in it so I have to stay on the case all the time to meet their high standards! As far as soiled areas outside of a litter box, the products available nowadays are fabulous at cleansing and neutralizing odor very easily - you probably have them.. Maybe things will also improve once the worms are gone. How is her remaining eye - does she seem to see very well these days? Is everybody spayed/neutered now? - in addition to the obvious reasons, cats that are "fixed" will have far far fewer medical problems (including far fewer cancers) than if they are not. In the long run. much less money and anxiety. I really hope Baby will be alright - sending tons of good thoughts for her, and for you. JJ p.s. Anyone in my house showing lack of compassion would be the one in the tent (or beyond!) so I hope things get better there! I would never shun or allow the shunning of a 4 legged or feathered family member just because it developed a problem - that's when they need us most.
Diapers. http://www.planeturine.com/dsp_productUnit.cfm?productUnitID=34 We had the same problem with our old cat Gypsy before she passed on. She just didn't care where she "did it" anymore. So we used baby gates to lock her in an area that had vinyl flooring so it was easy to clean up. She went to kitty heaven a few months later. My wifes dog has "accidents" reason unknown. So we lock them out on the deck and they have a doggy door into the hallway which is all vinyl flooring and heated. When we come home from work they're allowed in to the regular part of the house. This really cut down on cleanup. If you have cats or dogs, the best tool you can own is one of those home sized carpet cleaning machines, they're great for cleaning up the oopsies.
We had a problem with one of our cats peeing outside the litter box for a while. What worked for us was getting a much larger box. We now use a sort of plastic storage tub. The other litter box we had was an "extra large" size litter box, but apparently our fussy girl kitty thought it was just too small. (Our boy didn't have a problem using it, even though he was larger than she was.) I guess she felt she needed more room to maneuver. A friend of mine at work had the same problem with her cat, and when I suggested this to her a couple years ago, the problem disappeared for her as well. I'm not saying the worms aren't a problem, but maybe getting a big tub would help, too. Good luck! I hope your kitties will feel better.
I know this is hard, but have you got enough space for a few litterboxes??? With my persitting business, i have found success with the same problem by just adding one more box. some cats will not share their trays!! good luck. Get her inside!!
In the last couple of years my old cat (13 this year) had developed a habit of peeing in the sink. She would do her other business in the litter box, but we couldn't break her of peeing in the sink. She past away last Tuesday night, we knew it would happen when she totally stopped eating on Monday, turning down her favorites like tuna and cheese. I don't think this is whats happening in your case.
i realize these same suggestions have been given before. But from my experience with kitties, medical reasons could be either a urinary tract infection or diabetes. On the emotional side, adding extra cat boxes can really help. The rule of thumb is one cat box per cat, and then an extra if you have the room. i have three cat boxes for four cats and am lucky that is enough. If you have a cat that is bullying your girl, then perhaps an extra cat box in another location would work. i had one small cat that was being bullied and she ended up living in our spare bedroom for the duration of her life, and was much happier that way. We were lucky we had that extra room. Good luck with your kitty!
