Labored breathing in a cat only 3 years old, cause?
If My Pet Has Labored Breathing, What Could This Mean?
This happens when a cat undergoes some stressful event that is not compatible with its nature. As you specified about its blood work and dental work, I must quote few of the reasons creating this stress in feline.
Bathing
Cleaning of teeth
This type of activities create problem of increased heart rate and heart gets less time to fill. The severity of symptoms varies from cats that appear totally unaffected to those who die suddenly. A mildly affected cat could very possibly lead a totally normal life. These cats may be identified only when symptoms suddenly develop due to a stressful event, such as bathing or teeth cleaning. Stress causes an increase in the cat's heart rate, which means there's less time for the heart to fill. If your cat is also showing symptoms like appetite loss, gagging and reluctance in movement along with breathing problem then there are more chances of heart problem. It is better to take it to vet for its heart check up.
