Chiko

Chiko was a cat living in Dublith under the care of a young girl named Menny. Though Menny cared deeply for her cat, the pet's life ran down and she apparently died of natural causes. But, too young to fully comprehend the concept of death, Menny brought Chiko to the home of alchemist Izumi Curtis so as to have her repaired, where Izumi explained that a life is something that cannot be regained once it has been lost. In consolation, Izumi helps Menny fashion a grave for the beloved cat and lays Chiko to rest in peace.

In the 2003 anime, Chiko gave birth to a number kittens, and one had managed to get precariously caught on a rooftop. Ed used his alchemy and agility to rescue the kitten, which Menny cuddled at Chiko's grave while trying to come to terms with her loss.
