Nausea is a feeling of unease or discomfort in the stomach that often precedes vomiting. It can be accompanied by symptoms such as dizziness, sweating, and a general feeling of being unwell. Retching, on the other hand, is the act of attempting to vomit without actually expelling any stomach contents. It is often characterized by the rhythmic contraction of the abdominal muscles and can be accompanied by a gagging sensation. Both symptoms are commonly associated with gastrointestinal issues, motion sickness, pregnancy, and certain medical conditions. **

There are a few potential reasons why your cat may be wheezing and retching but not vomiting.

Additionally, respiratory infections or allergies could also be causing these symptoms. It's important to monitor your cat's condition and consult with a veterinarian to determine the underlying cause and appropriate treatment. **
