The greet.css and greet.css are DRY.
Because it does not repeat again the same code logic, and it refactors the existing code.

the pet.css and pet.js are not DRY:
pet.css a possible DRY version :
.pet {
font-family: "Times New Roman", Times, serif;
font-size: 1rem;
}
.cat { color: #FFF; }
.dog {color: #000;}
.dragon {color: #009933;}
pet.js a possible DRY version:
const pets = ['Cat', 'Dog', 'Bird', 'Fish', 'Frog', 'Hamster', 'Pig', 'Horse', 'Lion', 'Dragon'];
// Print all pets
pets.forEach(pet=>console.log(pet));
