Answer
Heather,

Keeping her in a safe room  until after she is spayed and the stitches are out is probably the best thing to do.  Cats have a very complicated, noisy "getting to know you" ritual they go through.  Once Lily is let out of the room, you will need to ignore any and all noise.  Any human intervention will just prolong the "getting to know you" ritual and will be counter productive.  So, they just will need to be allowed to settle their inter-relationships however they will.

Given their ages, it may take a number of weeks or even months for for things to settle down.  It is possible, but unlikely, that Lily may not fit in at all, you will just have to wait and see.

Please let me know if you have any more questions.

Best regards... Norm.
