Gryphon got out this morning/afternoon sometime before 2:00 p.m. Our cleaning lady arrived then and he wasn't home, and she said the door wasn't completely shut (why she didn't call us, I don't know).
I live in Englewood, New Jersey. If anyone has any news, please reply.
I've called the police, animal shelter, vets, and posted on Craigslist. Any other advice, let me know. He is microchipped. He has a collar but no license since he chews them off (yes, he actually has chewed off three tags on his collar, both ID and rabies ones. After the third one I gave up. If you want to flame me for that, you suck so hard).
Here is a picture:
