From: http://www.wildlifenews.alaska.gov/index.cfm?adfg=wildlife_news.view_article&articles_id=145&issue_id=26 May 2005.â€œWeâ€™ve had several incidents where it appears people have released pet rats,â€ said Meehan. â€œPet rats are illegal, unless they are albino white rats. Some rats that have seen â€“ in Anchorage, Kenai and near Wasilla â€“ appear to be pets that were released or escaped.
If those get established, thereâ€™s a real wildlife concern. Plus these are near communities, and thereâ€™s whole other set of people-related concerns.â€
