Cheese Dragons are not actually alive. They are enchanted items of food that act almost identically to dragons. They have no need to eat, but they must “live” in humid environments or they will dry out and harden.

There was a White Dragon called Cheeth who was the mate of another White Dragon, Uldorth. She met her untimely death in a thunderstorm. Bereft, Uldorth asked her mistress to revive his fallen mate without success. Being unable to bring her back himself; he found an egg-shaped cheese in his mistress's pantry. Using every ounce of his magic, he poured his memories of her, all her memories of him, her sense of self even, into the 'egg' hoping to create something to replace his fallen mate. Although successful the resulting 'dragon' was incapable of breeding although Uldorth has been known to insist that it did happen but no eggs were produced.
