I just started doing Cairos last week. I picked up a bottle of the green OPI 'Pawlish' for her. It looks sooo cute!! And the best part is that I can use it too. I put it on my toes so we would match.
I find it best to wait till she is sleeping and use a super tiny hair clip to keep the hair off while I paint the nails. I think I got more polish in her hair than I did on her toes the first time
