Good question...hmmm. I know if it's YouTube or Ebay, etc... you report it to the host of the webpage.
But, if this is an individual web page, I would look for any service that supports it. For example, my IP gives me a free webpage to use for personal content such as posting wedding photos, etc... I don't think they'd be happy if I put something like what you described up.
The FCC is for television and radio. If this involves animals, maybe the HSUS (Humane Society of the United States).
I really have no idea.

Good for you though!
