hope someone can help me,ive got 2 cats one is a male ginger tom aged 2 and my other cat is a female exotic shothair aged 1 year,we decided a while ago to get a puppy and so got a 9 week old shih tzu last week,he is so sweet and very loving,my ginger tom cat is really bothered with him but my female cat isnt very happy,she has stayed upstairs in the house for 5 days now

she is eating well(we are taking food to her)and she seems well in herself dosnt seem tense or stressed,but when we try to introduce puppy to her she just hisses and all her fur stood up

i really dont know what to do,has anyone else had this experience,i feel so upset that she is staying upstairs and im giving her loads of attention and reassurance,any advice would be fantastic,thanks for reading,x
