"Our cat eats cheese."
Translation:Il nostro gatto mangia formaggio.
It's been two years, but all the same: in Italian, for a reason that I don't know, they say 'the my' instead of 'my'. There are exceptions, though the only one that comes to mind is family - Italians say 'mia sorella' not 'la mia sorella', or at least that's what I was taught.
"Il nostro" simply means "our." In Italian, having "the" doesn't always mean you are talking about a specific thing. Think of words like "la frutta" which just means fruit, or "il formaggio" which just means cheese. It depends on context, and in this case, "the our cat" does not make sense, so one can reason that "our cat" is the proper translation.
