Until Asteria was 18 and Nessarose was 4 years old, their father, Xander Starkiller, had placed a ban on pets in the house. However, when the ban was lifted, the girls were given a credit card and told they could go buy pets. No one had actually mentioned a limit to the amount of pets the girls could buy, and they ended up buying an entire Pet Market, gathering all the animals within it save the snakes. 
As the years progressed and the animals bred, the zoo currently holds a few hundred animals. Below are mentioned a few notable ones among them:
- Mookah & Meekah, a pair of mookas.
- Nymeria, Ghost, Grey wind, Lady, Shaggy, their offspring.
- Jax - male and female.
- Llamas - male and female.
- Horses - male and female.
- Ponies - male and female.
- Tusk Cats - male and female.
- Hoth Dogs - male and female.
