He looks like like a young, fit, short hair. A little nervous eh? I have heard that it is best to put them in a small room, if possible, until they settle down a bit. Food, water, litter box, some pillows to lay on. We have only had our kitty 3 days and we let her have full run of the house immediately and then put her in a smaller room for a while. We saw her patrolling and marking everywhere and we saw that it was a little overwhelming for her, so we researched and then put her in the small room. She is just resting now instead of having to patrol and mark a large territory.
