The word "bushytailed" is often used to describe animals or people who are enthusiastic and energetic, particularly in the morning. However, there are several antonyms that convey the opposite meaning of this word. Some of these antonyms include lethargic, sluggish, apathetic, inert, listless, slothful, and uninterested. These words typically describe someone who lacks energy or enthusiasm, and may be feeling tired or unmotivated. While "bushytailed" has positive connotations, it is important to recognize that not everyone feels energetic and enthusiastic in the mornings, and that it is important to respect and support each other's individual needs and preferences.
