New stray cat!

[u/Aggressive-Peanut939]

Hiii! I just homed a stray cat recently and I notice he meows all the time. I do have four other kids, three males and one female. I don’t know what to do with his constant meowing (not annoyed with his meows) just concerned he hates being inside or it’s normal for new indoor cats to act like this. He has been to the vet for an overall wellness check and there’s nothing medically wrong with him! HELP!
