While both are liquids produced by the cat's urinary system, they have different compositions and purposes.
Urine:
* Composition: A complex mixture of water, urea, electrolytes, and other waste products.
* Purpose: To eliminate waste from the body.
* Characteristics: Usually clear or yellowish in color, has a strong ammonia-like odor.
Spray:
* Composition: Contains pheromones, a type of chemical signal used for communication. It also has a high concentration of proteins and a lower concentration of urea than urine.
* Purpose: To mark territory, attract mates, and communicate with other cats.
* Characteristics: Thick, sticky, and has a pungent, musky odor that can be very strong and difficult to remove.
Here's a simple analogy:
* Think of urine as a "garbage disposal" for the cat's body.
* Think of spray as a "communication tool" used to send messages to other cats.
