I (and my siblings) had a total of 6 hamsters. 4 died of old age, 1 suddenly bled out overnight, and 1 died pretty young, but nothing was obviously wrong, so I dunno.
My neighbors had more than a dozen rodents (including 5 guinea pigs). They all died horrifically, including 4 that were killed by mouse traps. Because of course you should have mouse traps, and also keep small rodents that you allow to escape constantly. As an adult, I think the parents were seriously negligent in teaching their children, and then also negligent in buying more rodents for the grinder after the first two or three met horrible fates.









Some laptops let you set a maximum charge for the battery at 70 or 80%, which is better for long term storage, and still offers the backup power supply if needed.
