Terraria 1.4 introduced a way to get a cat as a pet, which is certainly nice. An indifferent animal living in your town, silently judging you, is exactly what every game needs. You can’t just go out and grab one, however. If you want to get a pet cat, you will need to put some work in for it.
Up first, you need a Zoologist NPC in your town. For this to happen, you will have to fill in 10 percent of your Bestiary. Filling your Bestiary is quite easy. All you need to do is explore the world, kill creatures and monsters, and talk to NPCs. You can check your Bestiary in the main menu by clicking on the little book icon beside the trash can. To fully fill out a creature’s entry in the Bestiary, you will need to kill them numerous times.
When you hit 10 percent in the Bestiary, you can build a new house in your town, and the Zoologist will move in, and you can then purchase a cat license from them. It will cost 5 gold. The Zoologist prefers to live in the Forest biome, and the ideal neighbors will be the Witch Doctor and Golfer.
When you get the cat license, use it like any other item, and a cat will be summoned to your town the following day. You can pet the cat, and it will bring you presents upon occasion. Keep in mind that the Zoologist will only sell one cat license per world, so you won’t be able to have dozens of cats running around.
