Why do cats vomit with a bladder infection?

Cats may vomit with a bladder infection due to the pain and discomfort associated with the condition, which can lead to stress and nausea. Additionally, the inflammation in the urinary tract can trigger a systemic response that affects the gastrointestinal system. If the infection is severe, toxins released by bacteria may also contribute to vomiting. It’s important for a veterinarian to evaluate any cat showing these symptoms to determine the underlying cause and appropriate treatment.
