I almost adopted
this cat tonight.
Her name is Ivy, and I got to meet her. The owner was flabbergasted when Ivy came over to me and started licking my fingers and enjoying being scratched and rubbed; she said the cat wouldn't let
her do that.
So we tried an experiment: We brought Ivy over to my place to see how Maddy would react.
It was a disaster.

Everything was okay for about 5 minutes, while Ivy explored my apartment and I showed her human what my cat setup is (proving that there are cat beds, perches, lots of food and litter...).
And then Maddy let out a screech that must have scared the people across the hall. Ivy started growling, and Maddy was furious. Maddy started chasing her around the apartment, and she was
not playing.
So no adoption. It's an urgent situation, as the owner is having major surgery and won't be able to care for the cat during her recovery time (expected to last months). She decided to offer her for adoption and was initially glad to not only get an answer, but also because I live so close by.
Alas, it's not going to work. I hadn't realized how territorial Maddy has become. She might be able to handle a kitten if the introduction was extremely gradual, but an adult appears to be out of the question.
It's not all bad, though. Ivy's human and I have some common interests, so making a new acquaintance who might become a friend is never a bad thing.
