Los perros, las gatas, y los caballos son animales. < ---- I typed that
But it has this ------- > Los perros, las gatas y los caballos son animales.
In Spanish, the second comma doesn't necessarily need to be there?
people argue about whether it must be there in English
In fact, many English learners were taught that the second comma in a sentence like this is NOT necessary --though the textbooks told us to add a comma before an 'and' :P
Personally I think the english sentence should read "Dogs, cats and horses are animals". I think the Spanish translation is the same but it makes a little more sense to me.
