We now know that Siamese cats can live up to twenty years of age, thats a long time. You will get to spend many years together. Let’s learn a little bit about a Siamese cat to get a better understanding of them.

Siamese origin history

The Siamese cat breed originated from Thailand dating as far back as (1351 to 1767 AD). We know this as the Siamese cat breed described in ancient manuscripts “Tamra Maew” (Cat Poems). At this time the Ayutthaya Kingdom was the capital of Thailand King U Thong founded it. King U Thong was escaping smallpox outbreak and stumbled across the new land, in which he called in Ayutthaya, also known as Siam, and it became the capital of Thailand for many years to come. Bangkok has now replaced the Ayutthaya Kingdom as the capital of Thailand.

Health and behaviour problems of a Siamese cat

Compared to other typical breeds of cats, Siamese cats have a higher risk of developing neoplastic and gastrointestinal problems.

Siamese cats also can develop the vestibular disease. Other than the usual old age-related illnesses, All in all, there are no other serious illnesses. It may seem quite a lot; however, many different cat breeds have these plus more illnesses. Let’s go through each one so you can get a little better understanding of what they are. I have added a link showing the full medical explanation if you wish to learn in even more great depth from a reliable source.
