If it helps the kitten of mine that's gone already settled really quickly, less than 24 hours and she was sleeping in the resident cats bed (her new 'sister' is 5 months old so still a kitten) and said cat was relegated to the newcomers bed lol, fast forward a week and the 2 of them are sleeping on my friends bed together posing for a cute picture. I'm sure your little one is settled already :-)
