The Ragamuffin is a stunning, large cat breed that captures hearts. But size brings risk - heart disease, joint problems, and kidney issues are breed realities that demand financial preparation.
No breed-specific studies yet - unranked. Missing data is not low risk.
Measured risks
How often they happen is backed by published studies.
What is this?Hide
All cats [2] 1.2% (cats under 9) rising to 3.6% (9 and older), UK primary care (Conroy M, et al. 2019, Veterinary Record/VetCompass). PKD1 is a documented Persian-lineage mutation (UC Davis VGL PKD test), not confirmed in Ragdoll or Ragamuffin genetic studies.
Progressive kidney failure requiring dietary management and fluid therapy. Some generic breed profiles list polycystic kidney disease for Ragamuffins, but that mutation is documented in Persian-lineage breeds and hasn't been confirmed in Ragdoll/Ragamuffin bloodlines - this is the general all-cats, age-banded baseline instead.

Known risks
Well documented in the breed - but no study has counted how often.
What is this?Hide
All cats [3] 50-70% of cats over age 3 show some periodontal disease on exam (Lund EM, et al. 1999, JAVMA, general veterinary-practice population); no Ragamuffin-specific prevalence study exists.
Periodontal disease requiring professional cleaning or extractions. No Ragamuffin-specific study was found - this is the general all-cats baseline. Full profile →

Breed study Meurs KM, et al. (2007, Genomics 90(2):261-4) identified the R820W mutation in MYBPC3 as the cause of hereditary HCM in Ragdoll cats, the breed from which Ragamuffin was developed before the 1994 split; no independent prevalence study or systematic MYBPC3 screening program for Ragamuffin was found. Ask breeders whether their lines are MYBPC3-tested.
Thickened heart muscle that can cause sudden death without warning. The Ragamuffin split from the Ragdoll gene pool in 1994, before the breed-defining MYBPC3 mutation test existed - so the same hereditary risk documented in Ragdolls is plausible in Ragamuffin lines, but the breed itself hasn't been independently screened or tested at scale.

Breed study Veterinary-content breed profiles (e.g., PetMD) describe earlier-onset joint/arthritis risk tied to the Ragamuffin's large size; no peer-reviewed Ragamuffin-specific prevalence study was found.
Ragamuffins are a large, slow-maturing breed (up to 4 years to reach full size), and veterinary breed profiles note this size can bring on arthritis-type joint changes earlier than in smaller breeds. No dedicated Ragamuffin joint-health study exists. Full profile →
What is this?Hide
Not measured No confirmed Ragamuffin-specific prevalence found; general indoor-cat obesity rates commonly cited around 30-60% depending on study population
Excess body weight accelerates joint wear - a particular concern given the breed's size-related joint flag - raises diabetes risk, and strains the heart. No Ragamuffin-specific prevalence study was found. Full profile →
How we know these numbers
- Confirmed = measured or gene-confirmed specifically in this breed
- Breed study = scientists counted it in this exact breed
- Body type = comes from the cat's build - size, skull, skin
- Genetic risk = the gene is proven, the odds are not
- All cats = an average for all cats, not this breed
- Not measured = nobody has counted it yet

My mother-in-law's boxer. Problem. $1,200 in tests, no answers. Another vet solved it with $8 pills. When you're scared, you'll pay anything - and some vets price accordingly. So I built what I couldn't find: real costs, real exclusions, plain language. Not selling policies.
