Lost Pet: Hamm

Circumstances

He is an indoor-outdoor cat, we saw him Monday night and then he vanished. We just moved to the area and he’s been outside during the day and comes in at night. 
mom always watching him to see where he’s at. He usually follows me around the yard and plays with me throughout the day. 
We have a puppy that likes to chase him. Im wondering if she spooked him and he took off in the woods.
