Bear was the same way. I got him about a week ago&it took him a few days to adjust. At first he was very mellow&quiet, but in a few days his true self emerged&now he's playful, eats well, goes to the bathroom regularly&lets us know when he wants something or is lonely! Just give your bby some time. He's in a new environment with new people&new smells&he needs to get used to it
Congrats on your new bby. He's adorable!
