@InspectorCaracal every 1-3 years is just a hell of a wringer to put yourself through. i did it through middle and high school and i loved my ratties immensely but holy shit, it's definitely a pace where as soon as you feel you've got your feet under you again WHAM HERE'S ANOTHER PET DEATH.
i mean i may be biased because the rattie i bonded with most out of the pair (or more) was fucking *always* the one to die young through nothing we could do, but, y'know
