"They draw several cats."
Translation:De ritar flera katter.
I don't know if it is a good way to remember but it worked at least for me. Have you already learned the German word ritzen? It means something like making not too deep cuts. I imagined a Stone Age man sitting in his cave and drawing (ritzening) a picture with a flint in the wall. The first three letters of both - ritar and ritzen - are the same, this was enough for me to remember.
There's a song about someone who emigrated from Sweden to the US and who has forgotten most of his Swedish so he mixes in English words. So he writes that he ritar ett brev, which sounds funny because he's actually saying he's "drawing a letter". Don't know if it helps you, but that's what comes to mind for me.
