Peeing in the house.

I would like a REAL solution to this, without the standard answers or suggestions( which will be explained in the question ).

We have a few cats. The youngest being 6 yrs old, the oldest will be 14 in April. 2 of our cats, literally, are peeing EVERYWHERE. Following is advice from numerous vets, all to NO avail:

1. More litter boxes - done we have 5 that are cleaned 2x a day and 3x a day on the weekend

2. Move the boxes to a different location - done about 5 times a week

3. taken to vet for examination and possible prescription - done about 4 times for each cat. while on the prescription there is no pee, however, first day off, pee everywhere. Not one of the vets suggested either cat would need to permenantly be on the prescription ; they ALL said a week's worth should solve the problem.

4. Crating - pee the INSTANT they are let out of their crates. Now, they are not completely crated all day, they are let out in a room when we come home from work - they instantly pee on the floor with freshly cleaned litter boxes right there

5. Diet change - we have literally tried EVERY cat food available in Canada

6. Pay more attention to the cats - our cats are our lives, there is nothing more important to us than our guys. We shower them with love, attention and play with them EVERYDAY without fail.


We are at the point that we just want to throw them outside and let nature take it's course. Not ONE vet ( nor the animal rescue league ) in our city will let us euthanize them - they all say constant peeing is not justification to put them down.

THey have destroyed EVERYTHING we own : couches and chairs, TV's, computers, a $3000 DSLR camera and a $2000 lens, every article of clothing they can get at, our CARS on trips to the vet, hardwood floors having to be replaced TWICE after TWICE replacing carpet... I can go on for hours.

Total damage is ( this is not a joke number either ) over $20,000 worth of stuff that has had to be thrown out over the course of 5 years.

PLEASE HELP US!! We don't want to just abandon them somewhere but we are really at the point that it is our home or them.

My question: What can we do besides just throwing them outside?
