Thanks for taking care of this little guy! I foster for a few rescue groups in Hudson County, but don't know any groups that could help in your area.

If you don't get any good leads here, you could reach out to rescue groups in your area to see if they can help find a home for the cat. Petfinder.com is very useful for finding local rescue groups... here's what I found around Metuchen:
