Hi there
My kids were banned a short time ago for killing a cat.  I have sent a request through another link on your website, but have since found this forum.  Sorry, if I'm doubling your work.
We only started playing on your server yesterday.  I'm not really too familiar with minecraft on a whole, but we went over the rules yesterday before they started.  They are telling me they can kill wild animals for a variety of purposes?  One thought this cat was wild, one thought it was a pet. Once the cat was killed, my son told my daughter that it was someone's pet.  She told the person that she had killed their cat.  I think she also said ha, ha.  I have explained that this is inappropriate and that this world relates to real life, and that we follow the same rules as we do in reality.
I've been really impressed with what my son has been doing on your server today, so I'm really hoping that they may get a pardon on this occasion.
Thank you for your time.
