This may be more of a WWYD. The lady next door has gone away with her children. She told me that she was going away and that her DH would be at home as he has to work. She is the one that normally looks after the guinea pigs.
They have been out in their run in the same spot since she went away. They have shelter but I don't think they have had food or water since saturday when I saw him out in the garden. He was out all day saturday and all day yesterday although did come home late last night. Their food bowl is empty, and I suspect that their water bottle is empty too (although can't tell). There is hardly any grass left. She normally moves the run around the garden. His car is not there this morning, so he must have gone to work.
Now I am a bit of an animal lover and this is upsetting me (easily done). Would I be unreasonable to knock on his door when he gets home and tell him to feed and water the guinea pigs? We get on ok as neighbours.
