Good luck with this one. Of course you realize she is bonding to
you...the next person needs to know they may well have to earn her trust.

Soon you might try introducing Red Tongue to others, while still in her
cage. Arm them with treats; food is love for felines. Then loads of lap
time.

Anecdote: We had one guy, years ago, who bonded to the household cats
(one in particular) but would avoid me. In his case, I simply shunned
him, providing for his physical needs but not speaking to him or touching
him or even making eye contact. After just a few days of this, he
approached me while I was sitting in the living room. I ignored him. He
stood by me and meowed. I ignored him. He jumped up beside me and meowed
again. I ignored him. Then suddenly he yowled! right in my ear and poked
me with a paw. I immediately turned to him and began to pet him while he
purred. The connection was made.

Good luck.
