Health problems linked to the Maine Coon

Conditions and what they can cost
ConditionWhat it isRelated costs
Hypertrophic cardiomyopathy (HCM)Named by: PetMD vet-reviewed guide [1]The heart muscle thickens and stiffens. It is the most common heart disease in cats and can cause heart failure or blood clots. [2]Cat heart ultrasound (owner bills): $90–$400 [3]
Polycystic kidney disease (PKD)Named by: PetMD vet-reviewed guide [1]Fluid-filled cysts grow in the kidneys from birth and slowly lead to kidney failure. A DNA test and ultrasound can screen for it. [4]Kidney disease care, per year: $400–$1,200 [5]
Cat ultrasound (owner bills): $90–$400 [3]
Hip dysplasiaNamed by: PetMD vet-reviewed guide [1]The hip joint forms loosely, so the ball and socket rub and wear. Over time this usually leads to arthritis and pain. [6]X-rays: avg $493 (range $56–$1,000) [7]
Dental diseaseNamed by: PetMD vet-reviewed guide [1]Plaque and tartar build up below the gumline and lead to infection and tooth loss. Small breeds and some cats are especially prone. [8]Cat dental cleaning (owner bills): $350–$1,450 [9]

Costs are national figures from our sourced cost guides, not breed-specific prices. Being on this list doesn't mean a pet will get the condition.

PetMD's vet-reviewed guide to the Maine Coon lists these conditions to know about: Hypertrophic cardiomyopathy, Spinal muscular atrophy, Polycystic kidney disease, Hip dysplasia, Chronic gingivitis. [1]

Health screening

The UC Davis Veterinary Genetics Laboratory lists 4 DNA health tests for the Maine Coon, including Progressive Retinal Atrophy (PRA rdAc) (Abyssinian); Polycystic Kidney Disease (PKD1); Hypertrophic Cardiomyopathy (HCM) in Maine Coons; Dilute. [10] One health test costs $47 there. [11]

What to budget

Breed-specific cat bills aren't published, but a routine vet visit for any cat typically runs $190–$525. [12]

Lifetime cost, roughly. Our yearly estimate for an adult Maine Coon at US-average prices, before insurance, is $800–$1,300. Multiply that by a life expectancy of around 13 years and you get roughly $10,400–$17,200 over a lifetime, before inflation and before any major illness. The low end is the ASPCA's yearly cost of care; the high end adds one typical vet bill a year. [12][13] It's simple math on sourced figures, not a quote.

Insurance and savings

The average accident and illness policy cost $435 a year for a cat in the US in 2025. [14] Timing matters more than the price. A condition that shows up before you enroll is usually treated as pre-existing and isn't covered. [15]

Prefer saving instead? Putting money aside each month works too; see insurance vs a savings fund.
