Consider steam-cleaning the carpet. If the enzymatic cleaner didn’t remove the stain completely, consider renting a steam cleaner or hiring a professional to do the job for you. Make sure to ask if they have a product to add into their solution designed for pet stains. Stains are a lot easier to remove when they’re fresh, so try to decide quickly if this is what you need to do.
Sounds good, but what about any discoloration damage to carpet if “enough strong peroxide” is used? You say use 30% H202, so is the 40 volume (assume 40%) clear developer from beauty supply too strong?

If you’re faced with set-in stains or smells you can’t get rid of, it may be time to call in a professional, as sometimes spot-removal isn’t enough, Hatch said. “Unfortunately, urine doesn’t just stay at the top of carpet, it soaks into carpet padding and backing and can even soak into the sub floor,” he said. Spot cleaning can only get the urine at the face fibers of the carpet, and to truly remove the bacteria and the odors they can create, you’ll need a professional, he said.
Wash your pet’s bed. This site of comfort can also be a site of stubborn pet odors.[6] Luckily, most beds can be machine-washed using a regular cycle and warm or hot water. Tumble dry the bed in the dryer.
Sounds like your kitty may need a new cat food. I have a lot of experience with cats, and most of the hairballs and vomiting stopped for us when we switched to a more natural food. We feed Diamond indoor formula, but any cat food whose main ingredients are meat rather than corn and wheat is likely to win you a reprieve from the constant vomiting. Just make sure you swap foods over the course of time rather than abruptly, to save on stomach upset. Yes, it’s more expensive, but the cat’s lack of vomiting (and the food’s lack of staining, if the cat does vomit) are worth a little extra. 🙂

I have three Scotties. Cushing’s disease will cause a dog to pee a lot, drink a lot of water and you should check with your vet for diagnosis and medication. Currently have one that has it and previously had one that had it. Evidently it is fairly common in certain breeds. And urinary tract infections will also make doggies pee more frequently.
I have come across a flash light like device that emits a “black light ” that when shined onto an area that has urine stains the light will illuminate with a bright light color making it possible to detect urine srains. This light is available on Amazon for about $7:00. Using in a darkened room will help spotting the stains easier.
I have been told by an animal behaviorist about this product for ridding your carpet from pee odors and poop odors. The product is called Anti Icky Poo (lol). It is organic and environmentally safe to remove odors. It is avaible at some pet stores or online.
Slowly pour your solution onto the site and gently scrub with paper towels or a soft brush. Let sit for 15 minutes, then dust with baking soda. When it’s dry, vacuum. You might need to do this a few times for tough stains or especially strong odors.

If you don’t have hydrogen peroxide on hand you can substitute it with a laundry spray stain remover. Check the bottle. If it says ‘Oxy’ anywhere on the label then it probably contains hydrogen peroxide. Preen, Sard, OxiClean etc.
(Explanation. Dish Soap or Dishwashing Detergent? Different countries call it different names. It is what you use to wash dishes in your sink. For example, Dawn, Palmolive, Fairy etc. Do not use Detergent that you put in your dishwasher)
It is also a good idea to empty the bladder completely when urinating, to avoid remnants of urine dripping on to clothing. Wiping well and rinsing with water, if needed, after urinating can also minimize the bacteria that cause infections and ammonia-smelling urine.
I don’t subscribe to the commonly quoted rule of drinking six to eight glasses of water every day. Your body is capable of telling you what it needs and when it needs it. Once your body has lost one to two percent of its total water, your thirst mechanism kicks in to let you know it’s time to drink — so thirst should be your guide. Or course, if you are outside on a hot, dry day or exercising vigorously, you’ll require more water than usual — but even then, drinking when you feel thirsty will allow you to remain hydrated.
Leather and leather-like fabrics are a little more delicate, but can still be cleaned. Make a solution of equal parts vinegar and water. Soak a cloth and wring out as much liquid as you can, so the cloth is barely damp. Then, wipe the surface of the fabric to remove any troublesome smells that are lurking.[4]
If the urine has soaked into the padding under your carpet, you may have no choice but to replace that area of the carpet and padding. Once the carpet pad is wet it is extremely difficult (if not impossible) to clean and dry it.

I​’m interested in the intersection between design and technology​—whether for ​drywall or robotic vacuums—and how the resulting combination affects consumers. I’ve written about consumer advocacy issues for publications like The Atlantic, PC Magazine, and Popular Science, and now I’m happy to be tackling the topic for CR.

Clean your pet’s toys and accessories. Your pet is lucky to have a number of beloved toys and accessories. However, when unwashed and strewn about the house, these can create unpleasant odors. Wash fabric toys, ropes, towels, collars, and leashes in the washing machine. Tumble dry them in the dryer. Wash hard toys, bowls, and rubber toys in the sink with hot soapy water.
I didn’t have any fresh urine stains, but there is a spot that was my puppy’s favorite before he was fully house-trained. This product has a pleasant smell, and definitely gets rid of any doggy odor. I put two bottles in my carpet steamer, and the whole house smells great now. I tried it on a spot where my cats had a spat (cat spray!), THIS PRODUCT WORKED. The only reason it’s not five stars is because the bottles are TINY.
