Take it to the drycleaner and mention the pet stains when dropping it off.
It will most likely need to be washed to really get all the urine out, and most dry cleaners don't want to put urine in their solvent anyway. Washing will make the comforter smell much better, reducing your aggravation over paying for it to be cleaned and then still having an odor, and reduce the likelihood of your cat smelling the urine and continuing to urinate on the comforter in the future.
It would be advisable to take a large (Queen or King) comforter to a dry cleaners or a laundromat with extra large capacity machines for best results. Most home washer/dryers are not equipped to handle such heavy and large loads, and if there is not ample drying room in the dryer the comforter either won't dry, may damage the dryer, and have been known to catch on fire.
However, with washing a dry clean only comforter, you run the risk of shrinkage, color fade, the stuffing clumping, and depending on age and material, the fibers literally falling apart.
If the comforter's material is polyester and/or down, washing should be fine. Acetate, silk, or rayon run higher risks of the aforementioned risks.
I would suggest you have it dry cleaned and remember to tell the dry cleaner about the cat urine.
Go to the stain, fill a bowl with COLD water and nothing else, then take a clean, non-lint producing towel. Dip the towel in the cold water and rub the stain, repeat until the stain is gone.

Yes, it does. Don't smell it, just clean it up with a tissue.
Put dog outside where they belong and buy a new couch, because urine has ammonia in it and the smell will never go away only fade. Well actually....you can use 1 part vinegar to 2 parts water. Vinegar will remove the enzymes that make the urine smell, oh that would be the ammonia, and the smell will go. You will need to keep the dog away from the couch until it is clean and dry though, and then make sure it does not happen again.

There are many reasons why there could be a urine smell in the bathroom. If there is a warm air vent near the toilet, it is possible urine could have gotten into it. If your water comes from a well, the well may be picking up extra minerals. This can cause water in the toilet to smell like urine.
