bulletSix-month-old female spayed Domestic Shorthair cat ("Nimbus")

Presenting Complaints

bulletHeart Murmur

Pertinent History

bulletClient obtained cat from shelter one month ago. The shelter obtained the cat in November at 4 months of age. When they received her, she was febrile, lethargic, weak, and had hind-end pain. She was treated with antibiotics and fluids and responded well. Radiographs were taken at that time.
bulletWhen the client obtained Nimbus from the shelter, she took her to her referring veterinarian for an exam and vaccinations. The referring veterinarian interpreted previous rads as showing cardiomegaly and repeated rads, which were again interpreted as showing cardiomegaly. A III/VI systolic murmur was ausculted, and a radiologist performed a cardiac echo three weeks ago that demonstrated congenital heart disease.
bulletUpon presentation to the Cardiology Service today the client reports that the kitten is doing great at home. She is very active with a great appetite, no coughing, intermittent sneezing with no discharge (~10 sneezes/day), no v/d/pu/pd. Occasionally acts like she is trying to bring up after eating dry food (3 occurrences in last month). Owner has not noticed any respiratory difficulties or exercise intolerance.
bulletShe is spayed, and currently due for her third FVRCP vaccine.
