New cat and behavior question

[Karen]

Awww, bless you, he looks like a little sweetheart. As Sandie said, it will take time. Moving things that smell like him out to where the other cats are and vice versa will help them get accustomed to each other more, as Sandie mentioned. Glad Lyra likes him already and vice versa!

This will take time as the little Cat may think of the Bigger Cats as potential enemies if he has had past bad experiences with larger Cat.
Keep them seperate until they get used to each other , and be patient.
