I would think it would be obvious to prove any one of us were not mistreating our animals... just like in cases of child abuse, the authorities check out the complaint and verify whether abuse was actual or not.

I do think it IS our responsibilty to watch out for the welfare of our neighbors... whether they be human or animals. Too often people turn a blind eye to harm and then later regret it when something really bad has happened.

I would most definately take the poor kity to the vet and let the proper authorites come along to make sure this cat has the chance to live a healthy happy life. Catmandu, you have such a wonderful heart, I hope the kitty will be ok.
