Hello Alien Mama!

Great questions! Aliens can have pets, but only on the Catgirls home planet. Catgirls are restricted from ever leaving their solar system of origin. A rule that applies to all the species the humans have conquered, save one. Dogboys were the first ever species humans chose to enslave, turning them into their ground fighting force during the Endwar between all the other species in the galaxy. Since Dogboys still make a notable part of humanities military might, they go where needed.
