I'm To'resk orianted so for To'resk mounts I think the Otter bear will be common since it is semi aquatic.
As for pets, I feel the to'resk would value flashy vanity pets, like colorful parrots, peacocks, maybe even small jungle cats from the Janoa jungles. Other pets could maybe be monkeys instead of lemurs and river otters or colorful lizards. Turtles could also be a pet, but the to'resk might paint and decorate their shells to make them more colorful.
I'm interested to see what the devs come up with however
