Aaaaaand we're gone :/

[Jax]

We (my husband and I) purchased our first snake from the Denver Repticon about 2 weeks ago. Jax is a two year old spotted python and is around 3 feet/3.5 ft long. Wewake up this morning to find he had pushed his enclosure door open and is subsequently missing (pretty sure my husband forget the lock). I've been up since 5:30 searching for Jax having zero luck. What worries me is he got out of our apartment (750 sq ft) via a hole in the bottom of our heating vent or through the front door (the gap isn't very large at all, but I watched him squeeze into the crevice of our sectional ). Time is a bit of the essence here because we can't exactly ask any of our neighbors if they've seen a 3 ft python slithering around (most of them don't speak English... and I'm pretty sure we aren't supposed to have snakes). I've read about setting traps and everything but honestly at this point what is the likelihood Jax is still in our apartment: /? Second if he is still here...I'm worried that at night my 3 lb red satin (rabbit) might look like a tasty snack: /. I'm really desperate to find Jax or to know of we should just right him off as a loss as someone has probably already seen and killed him?
