I'm starting to completely worry I've done the wrong thing bringing a kitten into the home.
I know it's early days but I'm a worrier by nature!
We brought home a 9 week old kitten to my older (9ish) female today and while realistically it's been OK - I'm thinking it may never be as good as I hope.
I did a fair bit of research beforehand but living in a 1 bed flat, I'm not able to fully follow recommendations of introducing a new cat.
we've separated the kitten into the living room while the older resident cat has the other rooms - she initially hissed at the kitten as we brought him in the carrier then hid under the bed for a few hours.
She's now explored the living room (kitten can't get out of that room but the resident cat can get in) while he's asleep and sniffed around. When she saw where he was sleeping she approached and hissed - then ran into the bedroom where she ate some food and is now sat on the bedside table.
It has only been 10 hours - should I be worried by her reaction?
Is there anything I can do to help? Should I interfere when she does hiss/approach the kitten?
(I will fully close the resident cat in the bedroom and bathroom when I'm asleep/not in the flat for now.)
