a died animal laying on the street

Sometime I will think when will the dead body of the animal laying on the street as I always seen a frog laying there for weeks?

I felt pity towards them like when a person dies and that person didn't being buries properly, the spirit of him or her cannot rest properly.

Well, today I saw a KITTEN with its intestine out from the kitten ass hole making me think back the bird which I once saw in my hometown, the street nearby my home. The bird has just died before I was there because I saw the blood flowing out from its eyes and somehow a cat is going to the bird direction like wanting to devours it....
