One month ago, I decided to try Vegan Cat Food, so I bought some, and gave it to my cat. After she ate it, she went to sleep to her regular place.

Then, after a while I heard meows. But not a cat meowing, but a human imitating the meowing, and it was like the kind of terrified meowing. I quickly ran to the source of the sounds, which was the place where my cat used to sleep. Except there was an adult woman with cat ears and a tail, looking at herself, with a very terrified face, meowing. Fortunately she could be comforted with headpats.

She could adjust to her new form in a few weeks, although not without troubles. Even learned to speak (although she's still learning), shower (which she takes 3-4 times a day), get dressed, use and clean the toilet (where most of the conflicts came from), etc. She kept a lot of her cat-like behaviors, some of those were replaced by more human equivalents as time went on. Interestingly, she can still purr. She also often growls or hisses when she's angry or feels as threatened. She seems to be now possessing a human level intellect, which paired with her cat-like curiosity, means she can learn relatively quickly. She somewhat remembers her normal-cat days, and she's angry if I call myself her owner since she learnt the meaning of the word.

I have three concerns with her as of now:

1. While initially she was both scared and depressed about her new state, nowadays she says she's happier this way. However both of us are concerned about the longevity of her current state, with her having nightmares about it.
2. I haven't neutered her while she was a regular cat, so now she has a human-like sex drive, and is seeing me as a romantic/sexual partner. She gets jealous when I'm around human females (although not to a dangerous level), she often wants to headpat or bathe me, and often presents me her naked butt and genitals to do it with her. Fortunately she understands consent, but she hopes I change my mind about it. And I personally do feel something for her, she's pretty and stuff, but a month ago she was just a pet of mine.
3. I fear that the government takes her away from me to then experiment with her.

What should I do? Should I be concerned about other things?
