Photographing a skinny cat

Today I have nothing to do at home, just sleep all day.

when I was about to wake up and go to the front door of the house, I saw a cat who was pensive

This cat looks very thin, maybe it lacks food,

I don't even know where it came from to my house, could someone throw it away, feeling sorry I will try to take care of it.

thank you
