As a former site admin, I will say right now that leaving any kind of rule “open to interpretation” is the WORST thing you could do. The only interpretation of the rules of your site should be the your (the site admin’s) interpretation. That’s it. Rules should be easy to understand and easily convey the correct interpretation.
Leaving the rules open to interpretation only leads to disagreements and arguments. It is better for users to have concrete rules with a reliably consistent correct interpretation than for everyone to complain because their interpretation of a rule lets them do whatever they want. Just my two cents on that.
Yeah, the correct information was given by the admin’s decision to get involved. Feeding cats a vegan only diet is tantamount to animal abuse, via slow malnutrition torture.
