Siamese Are Social & Vocal

Siamese cats are highly intelligent and form strong bonds with their owners. They require significant attention and mental stimulation. Neglect can lead to behavioral problems and stress-related health issues.

What Makes Siamese Cats Unique

Siamese cats are one of the oldest recognized breeds with distinctive characteristics that affect their health:

  • Temperature-sensitive coloring: Point coloration linked to genetic mutations affecting vision
  • Wedge-shaped head: Modern Siamese have elongated features that can affect breathing and dental alignment
  • Lean, muscular build: Athletic body with higher metabolism than many breeds
  • Highly social nature: Extreme need for companionship can lead to stress-related illness
  • Vocal communication: Known for loud, distinctive meows used to communicate needs

Major Health Conditions

1. Respiratory Issues & Asthma

Common

Siamese cats are more susceptible to upper respiratory infections and feline asthma. Their elongated head structure and genetic predisposition increase their risk.

Watch for:

  • • Wheezing, coughing
  • • Labored or rapid breathing
  • • Sneezing, nasal discharge
  • Open-mouth breathing = emergency

Management:

  • • Avoid smoke, dust, fragrances
  • • Use dust-free litter
  • • Inhalers for asthmatic cats
  • • Prompt treatment of infections

2. Dental Disease

Very common

Siamese cats are highly prone to periodontal disease and gingivitis. The wedge-shaped head can contribute to dental crowding and increased plaque buildup.

Signs:

  • • Bad breath (halitosis)
  • • Red, swollen gums
  • • Difficulty eating or dropping food
  • • Drooling, pawing at mouth

Prevention:

  • • Annual dental exams from age 1
  • • Professional cleanings
  • • Daily tooth brushing if tolerated
  • • Dental treats and toys

3. Eye Conditions

Breed-specific

The gene responsible for Siamese coloring also affects visual pathways. Progressive retinal atrophy (PRA) and glaucoma are concerns, though strabismus (crossed eyes) is largely cosmetic.

Conditions:

  • • Progressive Retinal Atrophy (PRA)
  • • Glaucoma
  • • Strabismus (crossed eyes)
  • • Nystagmus (eye tremor)

What to do:

  • • Annual eye exams
  • • Watch for vision changes
  • • PRA has no cure but progresses slowly
  • • Strabismus rarely needs treatment

4. Amyloidosis

Hereditary

Siamese and related breeds (Oriental, Burmese) are predisposed to amyloidosis, where abnormal protein deposits damage the liver or kidneys. Often appears between ages 1-5.

Warning signs:

  • • Loss of appetite, weight loss
  • • Lethargy, weakness
  • • Increased thirst/urination
  • • Jaundice (yellow gums/eyes)

Management:

  • • Regular bloodwork monitoring
  • • Supportive care
  • • Dietary management
  • • Screen breeding cats' lines

5. Cancer (Lymphoma & Mammary)

Higher risk

Siamese cats have elevated risk for certain cancers, particularly intestinal lymphoma and mammary tumors. Early spaying significantly reduces mammary cancer risk.

Warning signs:

  • • Weight loss, decreased appetite
  • • Vomiting, diarrhea
  • • Lumps, especially near mammary area
  • • Lethargy, hiding

Prevention:

  • • Spay before first heat
  • • Regular vet checkups
  • • Feel for lumps monthly
  • • Early detection improves outcomes

6. Anxiety & Stress-Related Issues

Common

Siamese cats' high intelligence and social nature make them prone to separation anxiety, psychogenic alopecia (over-grooming), and pica (eating non-food items).

Signs of stress:

  • • Excessive vocalization
  • • Over-grooming, bald patches
  • • Eating fabric, plastic (pica)
  • • Inappropriate elimination

Prevention:

  • • Plenty of interactive play
  • • Consider a companion cat
  • • Environmental enrichment
  • • Avoid leaving alone for long periods

Bloodwork Considerations for Siamese Cats

When reviewing your Siamese's bloodwork, consider these breed-specific factors:

  • Liver enzymes (ALT, ALP): Monitor for amyloidosis; elevated values warrant further investigation
  • Kidney values (BUN, Creatinine): Siamese can develop amyloidosis affecting kidneys
  • Total protein/albumin: May be abnormal with amyloidosis
  • Stress hyperglycemia: Very common in anxious Siamese during vet visits

Use our cat blood test value checker to interpret your Siamese's results, but always discuss breed-specific concerns with your veterinarian.

Preventive Care for Siamese Cats

Daily Care

  • Interactive play sessions — at least 20-30 minutes daily for mental stimulation
  • Social interaction — Siamese need significant human or companion animal time
  • Dental care — brush teeth if possible, or use dental treats
  • Environmental enrichment — puzzle feeders, cat trees, window perches
  • Weekly brushing — short coat needs minimal grooming but they enjoy it

Recommended Health Screenings

Annual bloodwork
Monitor liver and kidney function
Dental exam yearly
Starting at age 1
Eye examination
Check for PRA and glaucoma
Heart auscultation
Listen for murmurs at each visit
Early spay/neuter
Reduces mammary cancer risk
Weight monitoring
Keep lean for optimal health
Senior wellness screening
Bi-annual exams for cats 7+

When to See the Vet Immediately

Emergency Signs - Seek Immediate Care:

  • Open-mouth breathing or severe respiratory distress
  • Collapse or extreme weakness
  • Jaundice (yellow gums, eyes, or skin)
  • Not eating for 24+ hours
  • Straining to urinate or no urination
  • Vomiting blood or bloody stool
  • Sudden blindness or dilated pupils

Frequently Asked Questions

What is the average lifespan of a Siamese cat?

Siamese cats typically live 12-20 years, making them one of the longer-lived cat breeds. With proper care, many Siamese live well into their late teens.

What health problems are common in Siamese cats?

Common Siamese health issues include respiratory infections, dental disease, progressive retinal atrophy (PRA), amyloidosis affecting the liver, and asthma. They're also prone to certain cancers including lymphoma and mammary tumors.

Why do Siamese cats have crossed eyes?

The crossed eyes (strabismus) historically seen in Siamese cats are due to a genetic abnormality in the visual pathway connected to their pointed coat gene. Modern breeding has significantly reduced this trait, and it doesn't typically affect the cat's quality of life.

Are Siamese cats prone to anxiety?

Yes, Siamese cats are highly social and intelligent, which makes them prone to separation anxiety and stress-related behaviors. They require significant social interaction and mental stimulation. Signs include excessive vocalization, destructive behavior, and over-grooming.

Do Siamese cats need special dental care?

Yes, Siamese cats are predisposed to periodontal disease and gingivitis. They benefit from regular dental cleanings, daily tooth brushing if tolerated, and dental treats. Annual dental exams are recommended starting at age 1.
