How make “I really like cats and dogs” into a metaphor and simile

"Raining cats and dogs" literally means that small animals are falling out of the sky. But, of course, this image of animals falling from the sky is a metaphor for very large, heavy drops of water (and possibly dark skies, since animals are opaque).

In a normal metaphor there should be no  word (like).

if you made this example try to change it, but if it is the teacher's question

Hope this helps!

what does the teacher mean

it is believed to be alfred, lord himself
