The Siamese cat is predisposed to getting adenocarcinomas of the small intestine. This is a certain type of cancer and in this case it affects the Siamese cat’s small intestine.
Compared to domestic shorthair cats (non-purebred cats) the Siamese is 3-8 times more likely to suffer from these cancerous growths¹. Other sources state that there is a “greater” incidence in Siamese cats².
The symptoms appear to be:
- long history of non-specific gastrointestinal disease (meaning vague intestinal problems)
- weight loss
The intestine can be palpated by a vet and a mass can sometimes be detected.
It appears that an operation is required to remove the cancer by removing a part of the small intestine and joining it up again. A Siamese cat can live for about a maximum of 2 years thereafter. It seems to be fatal and the only medical treatment might extend life².
I believe this disease is classified as a genetic disease (inherited).
