"Remember that the cat will die." Hello! I'm looking for a translation of the above phrase, like a memento mori, but referring to a character's singular cat specifically. This is for a work of fiction that I'm writing for fun, not profit. The cat is female, not actually dying, and the cat owner (male) is stating the phrase in a sarcastic tone to someone else (also male). It's silly, but I believe it suits both the character and the situation. Thank you for your time.
