Here's an update from Delilah's new "mom":
Delilah is doing quite well! She seems much more at home, and has a routine based around my work day. She spends her day on the 2nd floor, without the dogs but with my other cats - she seems to get along with them as she and one other have been together on my bed. I've carried her downstairs when the dogs are outside so she can look around. She's eating well and she purrs when I pet and talk to her. She's interested in her environment and what the other cats are doing in her new home.
