Good morning! Welcome to Just Answer, my name is*****'s very possible these changes are from stress, but the with any urinary changes in male cats I do recommend having a urine sample ran to ensure he doesn't have any crystals or inflammatory cells consistent with a condition called FIC that can cause life threatening urinary obstructions. Has Memo been urinating normally?
Oh I am so sorry to hear that, that is such a difficult situation.
