it's injured like it's scraped off half of its nose and at first I took it outside to the bushes and then I went outside to give it some water and it came right up to me squeaking again... so I'm thinking it isn't a wild rat but was a pet rat at some point... so I felt too sorry for it so I've put it in my cat box with a towel and some water and bread and put it in my bathroom... I think it's in shock... I feel really sorry for it and hope it doesn't die

here is a pic of it
