You know your neighbor left automotive liquids outside and yet you left your cat outside unattended for 3 days. Those are pretty important details.

Do yourself a favor and stop trying to post this all over the internet. You were neglectful towards your pet and it ended up dying, then you took it out on your neighbor and drive him to madness (literally). Everyone on Reddit now knows you’re evil now, so stop trying to get attention and sympathy and go do something productive with your time.
