Here in the U.S., spring has finally arrived. If you’ve had a cat urine odor problem since last fall or winter, and thought you’d cleaned up each puddle thoroughly, you may be discovering otherwise now the heat and humidity have returned.
This article briefly describes the different components in cat urine, and why it smells so much worse in warmer weather. This article also discusses the most effective cleaning solution to get rid of the odor and stain permanently.
Cat urine stains are tough to get rid of because it has five different bacteria strains. Two of these are associated with the cat’s marking scent. The others are in the cat spray, urine, and uric acid.
The sticky, tacky part of cat urine is urea. The pigment is urochrome, and then there are the uric acid crystals, which look like salt.
The first two components clean up rather easily. It’s the uric acid with it’s crystals and salt that linger, causing the continuous cat urine odor. These crystals are insoluble, and bond tightly to anything they land on. This is why you can’t successfully eliminate cat urine odor with common household cleaners.
The crystals are reactivated with moisture. And this is why the cat urine smell is stronger in hot weather – the humidity in the air reacts with the crystals, and you once again smell the cat urine stain – even though you’ve cleaned and cleaned that particular spot.
In order to completely eliminate the smell and stain, the crystals have to be removed from the surface they’re sticking to. The only effective cleaning solution is a pet enzyme cleaner that’s specifically manufactured to attack the cat urine components.
These cleaners are special enzyme formulas that consume the bacterial components – which finally removes the smell and stain. Common household cleaners don’t contain enzymes, because most messes don’t have uric acid in them.
There are several reputable pet enzyme cleaners available at your local pet store. Read the instructions carefully and follow them completely for best results. If the stain is very old, it will take several applications to completely eradicate the stain and odor.
