  In a Commander game, the defending player is the player Chatterfang is attacking or the controller of the planeswalker Chatterfang is attacking.
• WWizards of the Coast2021-06-18
  Official Ruling
  The additional Squirrel tokens won't have any abilities the other tokens were created with. Anything else specified in the effect creating the token (such as tapped, attacking, "That token gains haste," or "Exile that token at end of combat") applies to both the original tokens and the Squirrels.
• WWizards of the Coast2025-01-24
  Official Ruling
  You don't need to control the spell or ability that creates the tokens, nor do you have to be the one creating the tokens for Chatterfang's ability to apply. As long as the tokens are being created under your control, Chatterang's replacement effect will apply.
