Questions & Answers

  • Info on feline heart murmurs
    I have a 15 y/o domestic cat, female, who was diagnosed with a heart murmur about 6 years ago. It has grown in intensity since then, from a Grade I to, presently, a Grade IV (ish.. as my vet says). I am intent on gathering information on feline heart murmurs, and I understand that heart murmurs are well documented in dogs, but not in cats. Are there websites, or articles, or any information that you could recommend to read for those of us working with our cats and their murmurs?

Please do not use our site to attempt to diagnose or treat your pet. Your veterinarian is the best source of health advice for an individual pet.

Please do use our site to become better informed about the medical problems your pet may have. We will do our best to ensure that information presented is accurate and up-to-date. The most current information will be at the top of each page. Remember that veterinarians often disagree about the best treatments for pets. There are often several perfectly acceptable ways to treat the same condition. Just ask a lot of questions!

For all emergency situations, please contact your local Emergency Pet Clinic or on-call Veterinarian. Answers are not provided in real time. We can not guarantee an answer to every question, nor can we provide timely responses to urgent questions in many instances.
