Cats shiver just like humans do when chilled to raise body temperature through muscle movements.
Feeling Cold
Some cats tremble or vibrate their tail with happy anticipation or eagerness related to eating or other activities.
Excitement
Stress, noises, travel to the vet, or introductions to new pets can cause shivering in frightened cats.
Anxiety
Cats may shiver after trauma, during exams, or due to vestibular issues affecting balance and coordination.
Pain
Ingesting toxins like antifreeze can cause tremors, seizures, and shivering. Seek immediate vet treatment.
Poisoning
Systemic illness and fever often produce shivering along with lethargy and appetite changes.
Fever
Sedatives, anesthesia, and some medications may cause temporary shaking as a side effect.
