I regret to inform everyone that Gershwin has lost his valiant battle against velvet, severe emaciation, and general Petco care. While he was only with me for a few short days, his struggle to live was inspiring and I genuinely enjoyed taking care of him. He was a handsome blue fellow with funny fused fins and a fighter's spirit but unfortunately, his poor abused body simply couldn't continue on. I know that he is now at peace in a place where he'll never have to worry about nasty parasites or dirty little cups ever again.
You will be missed, little Gershwin.
Edit: Also, I really want to thank everyone who cheered for Gershwin and who gave me such great support during his short life. Thank you all so much.
