Well you guys were right he did come down by himself. Took all nite.

I went to check on him one last time about midnight and it looked like he was at the top of the tree, can't really be for sure all i could see was the light reflecting off his eyes (he's a black cat).
Someone let the dogs out during the nite but in the hour that it took for Mom to get the dogs and wait for the sun to rise he had gotten down and was gone. He is now back home and hopefully won't try that again.
