Hi. I got my kitten last weekend and she has made herself at home very quickly! When I am out she is kept in the conservatory with her litter box, food and water, toys and her basket. She seems quite happy there and sleeps there at night times too (I put a microwave heated pad in her basket at night to keep her cosy.)
I also have an older cat and though the two have been introduced I have not let them alone together as yet. The older one hisses and then runs away but I'm sure my kitten would chase him if I let her go!
Good luck with you new kitten and I hope he settles in very quickly.
