"Sí, yo tengo un gato."
Translation:Yes, I have a cat.
I tried "Yes, I do have a cat" and it was rejected. I flagged it for review, since it should have been accepted. Or am I missing something?
Did you write "I own cat"? You left out" yes"and although it can mean the same thing, and is what is said more often in English, "own" is incorrect here. You need to keep to the verb used "tener" (to have, of course). So "Sï, yo tengo un gato" is what you needed to write, and therefore your answer was marked wrong, because it's not acceptable.
