This cat was 12 weeks old and presented to the clinic for respiratory distress. The cat was open mouth breathing and the gums and tongue were already turning a light shade of blue. The owner reported that the animal liked to carry rocks around in its mouth. After the exam, the doctor decided to take a radiograph to check the animals lungs. As you can see from the film, a rock was found lodged in the trachea at the area of the tracheal bifurcation. This is just another example of why you should pay close attention to what your animal is putting in its mouth and if your animal starts vomiting or having trouble breathing it is important to seek professional help.
