I have 2 cats in the house, Alvin who is 9 yrs old and Prissy who is 2 1/2. There is a new issue that has just surfaced, one and or both of them are using other areas of the house as a litter box. I clean the litter box 2x's each day, so there is no need for them to relieve themselves elsewhere. Recently, 3 months ago we were adopted by a beagle, Claire, 8 mo's old. I think this has something to do with the "litter box" issue. Claire is not allowed to stay in the house, she comes in occasionally for a while.
both cats need to see a vet to rule out health issues such as stones or crystals in their bladder or urinary tract. You need at least one litter box per cat preferably. Even cleaning it 2 times a day may not be enough for one or both of the cats. the general rule of thumb for indoor cats for litter box quanity is one per cat and usually one extra. Some cats develop a liking as they get older to use one box for bowel movements and one for pee. i highly suggest getting another box and getting BOTH cats to the vet to rule out illness. Good luck
Cats are very sensitive to any type of sudden change in household routine, so it's very possible the new dog in the house has "upset" them and they are showing their stress by not using the litter box. I agree to have them checked by a vet, but if you discover they BOTH doing this, I doubt it is a UTI that is causing the problem. Most people don't realize just how changes in the household can upset kitty. People moving in, people moving out, family members fighting, a new pet coming in or a pet leaving. Any of those things can uspet the daily balance of the cats life and will cause these exact behaviors.
Normally, it will correct itself once they get used to the change, but in the mean time, you might try confining them to a small room and not letting them have full run of the house. I would keep the dog away from them as much as possible until things calm down. I do NOT recommend turning them into outside cats. That is really not the answer.
You might also try a litter called Cat Attract. I know many who have had much success with it, and the product is guaranteed to work or your money back.
Things to try: I realize it is not always possible... but if they find they have favorite places to pee where they are not supposed to. Place a small dish of food there. They will then think it is an eating place, not a peeing place. You might end up with 500 food dishes around your house. Silly, but it might work. You can do it with water too, if the dog will just eat the food out of the dish and spoil it.
Another thing that sometimes works, depending on the makeup of your house.... if they like to go pee in some "favorite spots"... put aluminum foil on the ground there. They will avoid walking on it because of the way it feels and at the very least... be scared away from the place.
I realize that those are for more "spot specific" peeing.
If they are mad because of your dog...make sure that you address the REAL issue which is jealousy. I have a cat room in my house that the dog cannot get to (cuz' it's the attic and the stairs are funky). So I make sure to go up there at least a few times a week and pay attention to my kitty away from the dog so she knows that she will always get her "mom" time even if the pesky dog is around. We play ball, or curl up and read, or watch TV. As long as the dog is nowhere to be seen, cat thinks she's very special. meanwhile, they will still be peeing all over the house... try to clean it up ASAP WITHOUT the cat seeing you clean it up. (Don't ask me why, this is what I was told) But you have to clean it with the kind of solution that removes urine stains.. I forget the word... embryonic??? (that hardly sounds right!!! Someone will think of the word) that way, it is as if it never happened. The cat is reminded of the bad behavior because of their scent that is left behind. if they never see it again, and they are no longer jealous, they won't think of peeing anywhere anymore... at least that is the theory... good luck!!!
LOL! I think your thinking of the term enzymatic? And that's a good suggestion. There are many products out there these days that do a very good job. Urine Gone is an excellent product, but a bit pricey. Another good one is Nature's Miracle. I just bought a new product from RevivalAnimal (new to me, not new in general) called Natural Touch Enzyme Odor and Stain Remover. It seems to work well also. I have alsu heard of the aluminum foil trick. Never tried it myself, but I heard that it works.
The litter boxes are kept in the basement, both of them love it there, nice and cool and lots of places to explore. I would never think of turning them into outside cats, both have been declawed and I love them to much to put them out.
I have figured out that both of them are "peeing" in places they shouldn't.
