Thank you Angie. I would love to think he will be here with me for a long time to come but his older brother was put to sleep with it aged 15mths. Dillon is now 11months and is already lethargic and not growing. My two new kittens are nearly as big as him and they are four months younger and girls. |

Thank you Kazz and Shelley. Shelley HCM is short for Hypertrophic Cardiomyopathy and is the most common heart condition in all cats. It is genetic although only 1 defective gene has been found in Maine Coons and a totally different one in Ragdolls. Considering there is over 430 known genes causing this condition in humans it is highly unlikely that they will discover all the genes that cause it in cats, at least not in our lifetimes. It causes thickening of the heart wall which restricts the ability to pump blood through the chambers of the heart. This in turn can lead to blood clots forming and lodging in the body causing extremely painful paralysis of the back legs primarily although the blood clots have been known to affect the front legs and also the brain. It can also lead to a build up of fluid in the lungs and/or chest cavity which leads to Chronic Heart Failure. If fact some kittens have been put to sleep with suspected FIP because of the fluid when in fact it has been HCM. Cats can live to a relative good age with HCM but the early onset cats, such as Dillon, don't have a good prognosis especially considering the family history that keeps coming to light from his maternal grandfathers side. An older brother and sister have both been put to sleep with it aged 15 months and 5 months and there have been other relations. I am no longer breeding from Dillon's mum and have had his dad screened by ultrasound and he is clear at the moment. Unfortunately the ultrasound will only show the status on that day. It has to be done every year at a cost of £277 a cat, that is with my Dillon's cardiologist the first quoted £650. The cat could prove clear for all of its breeding life and then say 2-3 years after he/she has been retired from a breeding programme. For this reason HCM will never be totally irradicated but hopefully the early onset HCM will be. Hope this helps. |
