Musya was discovered
May we add that he is still alive and well! Musya returned to the staff room one day and clawed at the glass door, attempting to attract Alice’s attention. Alice’s eyes welled up with tears the second she realized it was Musya. Her kitty was unharmed and without a scratch.
Initially, Alice intended to find Musya a home, but once this scenario occurred, she realized that giving up Musya would be her worst regret. Musya seems to have finally found a place to call home.
