Waaay off-topic, but my cat has gone missing .....

[Milz]

You might want to begin calling the animal shelters in your area and 
posting "lost" signs around your area. On the other hand, I had a cat, 
Melanie, who would take holidays anywhere from 2 days to 4 days and 
wouldn't leave home until the next holiday four months later.

Melanie was an indoor-outdoor cat in her younger years. When she was 
an old lady of 13 years, she became exclusively indoors (and 
exclusively the green armchair). My current cat, Ruthie, is about 15 
months old and is an indoor-outdoor cat too. Her kitten, Harry, is 
exclusively indoors in spite of Ruthie's efforts to introduce him to 
the garden. 

Oh, you should give Kali some extra cuddle time. She probably feels 
very alone and very afraid right now.
