Came here to say the exact same thing, I'd love for my rats to live even 6 years, I always find it a little disappointing so much research is done on them yet they still live such a short amount of time. I suppose a heart that beats at 320bpm doesn't help... Also: much love to my fellow ratto parents out there, best pet on earth imo.
