Now that little 7-8 week old Mina can come out and play, Vesper (17 years old) has not been happy. I caught some photos of the situation that pretty clearly show the state of affairs:

Uh oh, who is lurking behind her?

Mina responds by tucking down her ears and cowering... :(
I know that they have to work this out on their own, and it might never happen -- but if anyone here has successfully gotten an older female and a baby female to get along, I'd love to hear your tips.
Mina lived in our bathroom for about a month before we let her and Vesper out at the same time. Now that she is a little bigger, Vesper seems more angry than she did when she was helpless.
Vesper hasn't actually attacked her yet, but she has taken a swat at her and growls menacingly whenever she sees Mina. Mina has gone from not really noticing Vesper to running and hiding (and staying as close to us as she can when she's not in "her" bathroom).
Last night they did briefly sleep on the same couch, but Vesper would wake up every few minutes and growl softly.
