Conclusion: Cohabitation of non-social animals CAN cause early death of an animal due to stress-induced feeding issues (including regurgitations), cannibalism, and/or breeding too young.
Just wanted to focus on the CAN part of the statement above for a moment.
Putting your snake in the perfect cage CAN kill it.
Doing everything to the best of your ability CAN kill it.
Doing nothing CAN kill it.
Not everything does though. Sometimes things that you, the collective you now, do not approve.
