Certain day in August 2011, I was fighting with other cats.
And lost the collar, and got an injury on my head.
My spare owner gave me a new collar, but did not find the wound on my head.
When I came back real home, the real owners found my new collar ,but it was a couple of days after that they noticed the wound on my head.
At that time, the wound was swollen that hurt just by a little touch.
Finally I could get here medication, and slept quietly all day.
