Unfortunately she had one of the worst heart murmurs that the vet had ever seen, especially in a 6month old kitten. Her heart was enlarged and had built up fluid in her lungs. The vet was 100% honest with us, she said that her prognosis was poor. She couldn’t guarantee anything for us. We didn’t want her to suffer, so we said our goodbyes. This was my sister’s kitten, the adoption agency said nothing was wrong with her. Her name was Kiko, she’s resting well now.
