There are two options:
1) Accept my new relatively carefree lifestyle and live out the rest of my days in pure luxury, not having to worry about food, water, bills, etc. The only problem is then I might miss some of the finer human comforts, such as video games, and get bored.
2) Jump on my owner's keyboard while she has any sort of text box open and type exactly what happened to me while she is watching. It's possible to do so without opposable thumbs, and what other choice would she have than to believe me? After that, I don't really know where my life would go. Scientific experiments? Still being a house cat but with my owner treating me like a person?
Honestly, I would probably go for option 2. I just hope that they wouldn't dissect me.
What an odd question, OP.
