Seeing stray cats living their lives makes me feel pity

‌Since they live on the streets, they are vulnerable to diseases and have a high possibility of dying from illness at any time.
Even if they somehow overcome a disease, they are only back to square one.
Then they have to go out looking for food and deal with territorial disputes among other stray cats.
In Korea, most people dislike cats, so you never know when or where a stone might be thrown at them.
In winter, they have to endure the freezing cold with their entire bodies.
Even so, I heard their average lifespan is only 2 to 3 years.
