Pets in ToG / Acotar

So my hobby is bookbinding and I really want to bind sjm books because I really liked reading them and want something unique. The first bind I did was for CC1, I used the otter for the cover (picture in the comments). I want to have all sjm with a pet (or something similar) as a cover but I need a few ideas because I read the books once and I can’t remember anything.

So what pets were in the books or wich animal would you put on the cover for wich book?
