Katy Cooper is a little girl who adopted Humphrey in "Squawk." She was voiced by Grey DeLisle.


Katy and her mother went to Shelter 17 to adopt Humphrey (after being called by Strudel), but when they arrived, Humphrey could not be found. In addition, McLeish was confused as to what they were talking about, and drove them away. Later though, thanks to Niblet's plan, Humphrey was able to find Katy, and she adopted him.
