Which health problems are common in the Siamese?
Often said to be more prone to feline asthma, though studies disagree, and the breed has a higher risk of breast tumors, which spaying early lowers. Noticing a cough early and feeling the belly for lumps are the habits that help most.

What should Siamese owners watch for?
Common for the breed doesn't mean your cat will have it.
- Feline asthma. Inflamed airways cause coughing, which can look like bringing up a hairball, and wheezing. Breathing with the mouth open needs a vet now.
- Breast tumors. More common in females that aren't spayed, and at a younger age than in other breeds. A small firm lump near a nipple needs a vet soon.
- Inherited sight loss (PRA). An inherited change that slowly damages the retina, with signs often from 1 to 2 years and sight usually gone by 3 to 5. An eye exam at the vet can see it early.
- Liver amyloidosis. A protein build-up in the liver that runs in some families. Drinking more, weight loss or yellow gums or eyes need a vet.
Which checkups do vets often suggest?
| Checkup | What it is | When |
|---|---|---|
| DNA test for PRA | A cheek swab, done once, that shows whether the cat carries the rdAc mutation for progressive retinal atrophy. | Once |
Your vet decides which checkups fit your pet, and when.
How do I keep a Siamese health record?
VetVitae, a free pet health record app for iPhone, Android and the web, shows these notes on your cat’s profile under Health, and Plan it opens the exam or test with its name filled.
For vaccines, parasites and the signs that can’t wait, see the cat care guide.
