Yowsers!!!! I really hope your snake simply escaped. Try looking close to the enclosure, they typically don't go too far. Start close and work your way out. Check EVERYWHERE. They tend to find dark, tight-fitting, warm places to hide, often where we doubt they can fit.
And this isn't a dig on you, but a great oppurtunity for a learning experience...
Enclosures need to be escape proof, because they are escape artist who WILL eventually find their way out.
Also important to point out: snakes and other pets don't mix!!! My other pets (cat, ferrets) are not allowed anywhere near my snakes or their enclosures. My snake room door is closed at all times. If a snake is out, no other pets are.
We see too often people posting pics of their cats sitting on snake enclosures, or snakes with other pets nearby. It's simply a BAD IDEA.
OP, I wish you all the very best finding your snake, hopefully it's simply an escape and you'll find him.
Good luck, please keep us posted.
