On page 180 it says:

If you’re a fan of fluffy felines, you’ll be starting here.
pets/v1/src/main/kotlin/com/example/pets/PetService.kt
const val url = "https://api.thecatapi.com/v1/"
Or, if you’re all about those cuddly canine companions, just swap that line
for this one.
pets/v1/src/main/kotlin/com/example/pets/PetService.kt
const val url = "https://api.thedogapi.com/v1/"

However, the source code has two objects:

object Cats {
  const val url = "https://api.thecatapi.com/v1/"
}

object Dogs {
  const val url = "https://api.thedogapi.com/v1/"
}

with the URL that is used being decided by the import in the file:

import com.example.pets.Dogs.url

So you’ll likely want to update the text on pg 180 to indicate you make the change by changing the import.

p.s. Cats are OK, but Dogs Rule!
