hi, my name is loretta and my beautiful cavie is Louis. he is the most lovable, loyal friend and is such a character, but this week we had to bring him to the vet as he was unwell and the vet delivered the awful news that he has a heart murmur. He had xray and blood tests on Wed and his heart is enlarged on the right hand side with fluid build up in the lungs. He has been prescribed heart medication and diuretic and will take them for the rest of his life. He will be five in August. The vet has confirmed that it is a common defect with cavaliers but I hope you can enlighten me as to what I can do to make his life more comfortable with the hope of having Louis around for a long time to come.X
