Cats, like dogs, talk with different felines by their scents. One of the cats’ scent-marking behaviors is spraying urine on vertical surfaces reminiscent of partitions, sidewalks, and furnishings. 

Female dogs urinate on the bottom, whereas males elevate a leg however don’t spray it. Although spraying performs a necessary position within the feline world, it typically poses challenges for its homeowners due to its robust and pungent odor. 

Cat urine has a a lot stronger odor than that of dogs, whose highly effective noses accumulate info from the aromas of different canines that had been outdoor like newspaper readers learn the information.  

Notably, sprayed cat urine has a extra pungent odor on the human nostril than regular urine of their litter bins. While it’s believed that sprayed urine comprises further chemical compounds probably derived from anal sac secretions, scientific proof supporting this stays unclear. 

Researchers study the explanation for sprayed urine odor

Japanese researchers examined why the sprayed urine had a particular odor in comparison with their regular urine.They have simply printed their findings within the Journal of Chemical Ecology, titled “Sprayed urine emits a pungent odor due to its increased adhesion to vertical objects via urinary proteins rather than to changes in its volatile chemical profile in domestic cats.”

The researchers initially in contrast the chemical profiles of risky natural compounds emitted from sprayed urine, regular urine, and bladder urine collected utilizing ureteral catheters.

Chemical analyses revealed a excessive diploma of similarity in these profiles throughout the similar people. Behavioral analyses additional demonstrated that cats perceived the sprayed urine and urine remaining within the bladder after spraying as related odors, whereas the odors of one other cat’s urine had been perceived as totally different.

According to Prof. Masao Miyazaki, a frontrunner of the analysis venture at Iwate University, some 500 kilometers north of Tokyo, the information point out that the sprayed urine originates from bladder urine with out supplementation with chemical compounds from different secretory glands.

Given the excessive diploma of similarity of risky chemical profiles between sprayed cat urine and naturally regular urine, researchers examined why sprayed urine emits a pungent odor from one other perspective.

They noticed that urine samples simply adhered to the internal floor of plastic syringes once they transferred the samples into glass vials for urinary risky analyses.

“This observation prompted us to explore the underlying mechanisms, ” mentioned Reiko Uenoyama, the paper’s first writer. Two many years in the past, Miyazaki found that wholesome cats excrete a considerable quantity of a urinary protein named cauxin (“curiosity” in Japanese), which contributes to the manufacturing of sulfur-containing odorants answerable for the distinct catty odor. 

“Generally, the wettability of a liquid on a solid surface increases as the surface tension decreases. Based on this knowledge, we hypothesized that the high protein concentration in cat urine might reduce the surface tension of cat urine, enhancing the emission of urinary volatile compounds from the large vertical surface area that was spread over the urine,” she mentioned.

As anticipated, the floor stress was diminished with growing concentrations of cauxin. At the identical protein focus, the wettability was increased within the cauxin answer than within the management answer containing albumin, a serious protein contained in mammalian blood. 

When evaluating the floor stress of cat urine with and with out proteins, they confirmed that urine with proteins exhibited considerably decrease floor stress than deproteinized urine.

Interestingly, the urine with proteins additionally demonstrated better adhesion to vertically positioned glass plates than the deproteinized urine.

In their observations, odorants answerable for the distinctive catty odor had been detectable in a synthetic miniature backyard designed to imitate pure environments during which a block sprayed with tomcat urine was placed. 

In distinction, no such odorant was beneath the detection restrict in one other backyard the place the identical urine was poured immediately into the sandy soil after which lined. 

“The difference in environmental odors between the two gardens, despite using the same urine sample, can be explained by most of the urinary volatile chemicals being trapped in the porous structure of the sandy soil. This phenomenon did not occur in the urine adhering to the surface of the block. Additionally, liquid droplets of sprayed urine can easily dry on the surface of the block, resulting in rapidly greater emissions of volatile chemicals from the scent mark than from normal urine,” Miyazaki defined.

In conclusion, the authors wrote that feline sprayed urine originates solely from the bladder, with none contribution from different secretions. Despite this unique supply, sprayed urine emits a robust and pungent odor owing to enhanced adhesion on vertical surfaces. 

Cauxin performs an important position in scent marking by not solely producing cat-specific odorants but in addition by enhancing the emission of urinary risky chemical compounds by growing the wettability of the sprayed urine. “These findings improve our understanding of the mechanism of scent marking via the spraying of urine for chemical communication in cats.”
