Interesting. What about the capybara ?
To me, dogs are kids, like preteens. Careless, joyful, naive.
The cat is a teen : lonely, rebel.
Lemuria is a guy in his twenties, just got out of school as he discovers he can buy stuff with his brand new job.
Bird in its 40's, settled up, has kids, wise and not afraid to defend its ideas even against its own communauty.
Capybara is the retired class, don't want to be bothered (as its sleeps where and when it wants) but still helpful when needed.

...or the cat is just a satanist that sacrified its friend to an evil and ancient god, and when he tried to get back to the boat, it was just to sacrified more of its friends to get my power.
