This clip comes from a user generated soundboard recording processed with a voice changer, which explains its pitched, artificial singing tone rather than a natural cat recording. No clear original source, creator or release context is known for the tung not here phrase, so it circulates mainly as a standalone joke audio. Short animal singing clips like this spread through shares and reuploads because they work without context, fit almost any pet footage, and can be reused as a quick reaction in memes, chats and short form video edits.
