Where cat urine is found, the cat odor cannot be removed, and the cat will pee there next time as if it has identified the territory. For many kittens at a very young age, the owner did not exercise their urination habits lead to the cat being very blind, they do not know where to pee.
So smell their smell and think that there is the toilet. To stop this from happening, in addition to exercising the cat, it is more important to remove the odor of the place where the cat has peed.

I. Why cat urine smells foul?

Cat urine is mainly composed of these components: urea, urobilin/urobilinogen, uric acid, sodium, creatinine, other electrolytes, bacteria, etc.
Why does cat urine slowly become dry, the longer it takes but the testier it is?
First, the urine is broken down by bacteria, making it smell like ammonia.
Then, as it breaks down further over time, it releases mercaptans, making the smell worse.
In addition, the urine of older cats (reduced kidney function) and male cats (testosterone) will be relatively more slutty...

II. Why is the urine smell still there even though it has been cleaned?

Water-soluble ingredients are easy to clean
The urea, urochrome/urochondrogen, creatinine, and pheromones in urine are water-soluble and can be cleaned with white vinegar, baking soda, detergent, etc.
But it is the water-insoluble urates that are the problem
Uric acid salts are insoluble in water, but they can bind tightly to any contact surface. The various types of detergents commonly used every day are unable to break down uric acid in urine.
And when dry urate crystals come into contact with moist air, they re-form uric acid and release the odor.
Therefore, in various studies, the half-life of cat urine can range from 2 to 6 years.
There is no urine smell, so why do cats still come here to pee?
Is there no smell? A cat's sense of smell is at least 6 times more sensitive than a human's (after all, there are 2 sets of olfactory systems and multiple plow nosers). Just because a small amount of uric acid releases an odor that people can't smell, doesn't mean that cats can't smell it.

Why is it useless to spray deodorant?
To get rid of urine odor, many pooper scoopers will choose to use deodorizers, air fresheners, avoidance agents, and other things, but why is it still useless after spraying?
The vast majority of deodorants are "germicidal deodorants", that is, to prevent the "bacteria stink". This type of germicidal deodorant product can only.
neutralize some of the water-soluble components in urine (white vinegar, and baking soda can also do the job).
Temporary masking of unpleasant and irritating odors (no product can mask for 2 to 6 years, and urates to fight a "constant battle").

Avoidance agents are used to preventing pets from entering a certain area after spraying on it, and most of their ingredients contain odors that cats hate (citronella, citrus).

It has a "masking" effect and should be sprayed after the smell of urine has been eliminated.

Air fresheners, as parents who have used them know: are unnecessary, really unnecessary. Because it just adds a strong new smell to the room. When it does not dissipate, the smell of urine + air freshener, the smell is touching; after it dissipates, the smell of urine remains.

All of these things can only remove and cover up the urine smell for a short time. To eliminate the urine smell, especially the stubborn urates, you have to use bio enzymes!
Bio Enzyme / Enzyme Cleaner is an effective ingredient that can remove uric acid/urate crystals.
The principle of action is to use protease molecules to break down uric acid in urine and make it evaporate.
Biological enzyme products are most commonly sprayed and also added to laundry detergents.

Three: What is the most important thing you need to do when you are bothered by urine odor?

While it's important to choose the right tools/products to completely remove urine odor, it's even more important to find the cause if you want to get rid of it once and for all!

(1) Urine odor from the cat litter box

The cat urine smell itself is natural (Lu Xun did not say "fart does not stink, it is a white release").

If the smell of urine from the cat litter box, parents need to do is: diligent shovel diligent cleaning!

If the smell of urine comes from the litter box, all parents need to do is: shovel and clean up! Attention

When using any odor eliminator, avoidance agent, or detergent products, try to dry the urine first, and do not spray directly on the surface of the urine or urine mass.

(2) The smell of urine outside the litter box

must be the first to line up disease problems
Almost all diseases of the urinary system and part of the reproductive/neurological/endocrine system may cause changes in urine volume and painful urination in cats. Cats may refuse to use the litter box because they "can't hold the urine" or because they mistakenly believe that "peeing in the litter box hurts".
When urination occurs, a urine test (additional X-ray + ultrasound) should be performed first to investigate medical problems.
Marking behavior? In heat? Anxiety?
The first step to solve the spraying of urine in heat, or the behavioral habits developed by long-term spraying, is de-sexing.
In addition, as if humans will scratch their hair or pick their fingers when nervous, cats will also mark to relieve anxiety.
Various types of environments, improper arrangement, stress/anxiety triggered by messy urination
Against the 17 possibilities listed, first, lock in 3 to 4 possibilities for adjustment and change one by one.
Cat urination is not revenge, attached are the most complete 17 causes and solutions!

The most complete list of 17 causes and solutions is attached! Note
Very often, the solution to behavioral problems is to determine the cause only after "eliminating multiple possibilities locking a small number of possibilities trying to change problem solving".
So, you have to try.
In addition, keep the number of factors that change at the same time to 1~2, to prevent the cat from becoming anxious due to too many factors changing and the environment changing on a large scale.

IV. Ways to get rid of urine odor
