Sorry for your loss, especially so sudden :(
Lost our family cat last year as well at the age of 25 but it was inevitable and we saw it coming in good time with many vet visits and attempts to prolong his life as long as he wasn't suffering/in pain so can't say I know what you must be feeling.
Sucks how there's still so many diseases and illnesses that aren't curable/cured, aside from all this negativity about AI with artists and authors complaining about it I do hope we get to see the good things of it in due time such as in the medical sector.
RIP
25?? If I was that cat I'd be going out pretty smug lol. Must have taken a lot of love to live that long!
Yah he lived quite a full and healthy life, Finnish cats are resilient I guess. :D
Might be the oldest cat on earth...a miracle
