When should we use past simple, and when past perfect? I've tried to make it up, but don't actually understand why and when we use each.
I (found) a kitten at the entrance of a friend's house.
It (fell) from a height of 1.7 metres and (had been) there for 3 (or) 4 days, in a cold, damp and dirty basement, without food and water.
On the fifth day we (found? ) it in the awful state.
Arthur ( got? ) him out of there.
It's body was completely lifeless. We (took?) it to the clinic and they decided to warm it up. The kitten (lasted?) for an hour and a half and (had died?) of exhaustion.
