The main reasons a cat's paws tremble include dreaming, parasite infection, calcium deficiency, and so on. However, the most common reasons are as follows.
1) Physiological factors: This is mainly caused by the cat's high activity level, such as accidentally twisting a muscle or becoming overly fatigued, resulting in trembling paws and legs. This is actually a normal self-recovery mechanism when muscles are fatigued. Generally, this is not a serious problem.
2) Psychological factors: When cats encounter new environments or strangers, they may experience trembling limbs due to nervousness.
3) Other reasons: If a cat's paws and feet twitch while it is sleeping, it is most likely that it is dreaming.
