These cards were made for a PAT (Pick-a-theme) swap. Instead of one overall swap theme, each player in a group (5 people) chooses a theme to which they'd like cards made. So instead of a few cards made to the same theme, you make one to each theme. Here, the chosen themes were cats (above), elephant(s),
(the fox was made as a hostess gift)
horses and Game of Thrones.
Funny enough, everyone in our group chose animals except the GoT person. My chosen theme was black birds (a common choice for me as I collect cards with black birds on them).
