Can you rename a cat?

[Snowflake]

I renamed both of mine, but they were very young and probably had no clue they had been named in the first place. Tango does respond to her name, but she also responds to brat cat and follows me when I call her. So I tend to think in many instances it is the tone of my voice rather than what I'm saying. Like that old Far Side cartoon, "What you say and what dogs (cats) hear" "Stop that bad Ginger!" "Blah blah blah Ginger"

Congrats on the new addition to the family!
