"Maybe the cats are not ours."
Translation:Forse le gatte non sono le nostre.
I wrote; può darsi che i gatti non siano i nostri. Since the sentence implies a doubt, I believe the subjunctive is the right answer. However, DL rejects it. and gives me this answer: Può darsi che i gatti non sono i nostri. sono is not the subjunctive but the present affirmative. Should I continue learning here where I am taught the wrong way?
Having read the comments quite far back, I still don't understand why Duolingo says that using the correct masculine plural for "cats" and "ours" is incorrect. In general speech, the masculine is used much more than feminine and is of course also used for plural nouns of mixed genders.
