Get "Nature's Miracle". You can get it at PetSmart. My 18 years old cat used my dining room as his litter pan the last two years of his life. The carpet was stained and the smell.....That's the first thing one would smell as they entered my home. I got the Nature's Miracle and also a stain remover by Lindhaus (I got mine at a vacuum cleaner/janitor supply business but you can get it online, too.) Anyway, these cleaned up my carpeting really good. I did use a steam cleaner on it, too. It took several applications over several months but my carpeting looks great and there is no odor. *They do have a Nature's Miracle for cats, too and this also works...even when a cat sprays!
I have used dry tide laundry soap before and that helped a lot.
Also, I did this before fibro and could not do it today, but maybe you can get help. It would get rid of the smell until you can put in new carpet, but is a lot of work. And it depends on what floor you have under your carpet. We have concrete floors. In my home office I just pulled the whole thing out: carpet, pad and all and threw it away. I cleaned the floor with bleach heavily diluted with water. Then got some inexpensive concrete paint and painted the floor. I used the kind that you put in one of those pump sprayers that sprays insecticides and stuff. You spray one color on then when that is dry, use a spray bottle to put on splotches of another color. Then seal it really good if you want it to last. If it is only temporary, you might not have to seal it. Then put an area rug down.
Best of luck!
I have used Nature's Miracle for years and for me it really worked, even on carpeting with padding. The only thing is, you need to let it sit for about two weeks and then reapply it. They have this black light you can get from the pet store, not buy it, just use it and it will show you where you have missed spots. I have had cats and dogs for over 25 years and plenty of them have had their share of accidents. I had a Bichon with an attitude that would pee in the house "just because" and he'd do it in our bedroom which was carpeted. Since he's been gone, I had the carpeting replaced and wondered about the floor beneath which is wood and there was absolutely no smell in it. My nose is super sensitive, I know I'd smell it if there was a smell there. I was buying it by the gallons, but you have to use it several times, especially if you have padding underneath the carpeting. As far as the kids, I don't know if it is safe or not. I would think the safest thing to do with small children would be to replace the carpeting or try to keep them out of those rooms, which I know would be really tough.

thanks, guys for all your help. I have heard about the vinegar-thing and will try that today. I live so far away from any Pet Smart or big pet store chain that I have had to use whatever enzyme Walmart carries. I am going to see if I can call a few stores in Syracuse and see if they have the Natures Miracle and the other things mentioned. I bought some Oxi clean pet and stain remover yesterday. The hubby doesn't teach enough classes over the summer to consider a new rug right now, but that is in our plan for the fall. We only have the one rug in the house...the rest is hardwood and Kid's and Pet's enzyme removed all the odor and stain off the wood.
