Poor cat~~~

Nowadays,
why some people is 'cold blood',
when see some animal,
they will try to kill it.
Just like,
last Sunday night,
I was going to my grandmother's house for my dinner.
When reach there,
I was saw a cat.
The cat was very special.
What so special?
That was the cat's eye was red in colour.
No one eye only,
but was a pair of eye.
Then I was thinking what was happen to it.
When having dinner,
my mum was ask my grandmother.
Now I knew why the cat's eye become red.
That was because,
when the cat enter her neighbours' house,
the people at there was catch it,
then use pesticide that use to kill mosquito,
to spray it's eye,
so the cat's eye was become red and blooding...
And the cat was pregnant-ing.
After my dinner,
when I went to see it,
it still can saw me,
but when I saw it's eye,
my eye start watering,
and it's voice was very low and low.
Just like a died cat.
Why nowadays people become so cold blood?
Is the animal disturb you?
Why should kill them?
Why can not live peacefully with animal?
