That adds nothing to Peter’s explanation in Acts 10:28, where he explains exactly what (or rather whom) God has cleansed instead of saying that God had cleansed the animals shown in the vision.
Acts 11:18 affirms this; the cleansing was upon the Gentiles.
I didn’t write it. I’m just telling you what it said. God told him to eat the unclean items because they were now clean. I assume He knew what He was talking about.
