[Veterinarian Explains] What diseases are Ragdolls prone to? Hypertrophic cardiomyopathy, urolithiasis, hairballs, etc.

The Ragdoll, whose name means "rag doll," is a cat that is truly like a plush toy: gentle in temperament and easy to bond with humans. They are highly popular in Japan, consistently ranking within the top 10 most popular cat breeds. While Ragdolls are generally easy to care for, they are susceptible to certain diseases, including hereditary conditions.

In this article, we will explain the diseases to which Ragdolls are prone.

Characteristics of the Ragdoll

The original Ragdoll cats were born in the United States in the 1960s. They were created by breeding a Persian with a Birman, and then crossing the resulting offspring with a Burmese.

They have large builds, with males sometimes weighing nearly 10 kg. They are characterized by their fluffy, semi-long coats. Known for their gentle and friendly nature, they are also said to be a breed that does not mind being held.

They are slow to mature, taking three to four years to reach adulthood.

Diseases to which Ragdolls are prone

Among the diseases common to Ragdolls, some are related to daily life, while others have been identified as hereditary. Conditions related to daily life include urolithiasis and trichobezoar (hairballs). Hypertrophic cardiomyopathy is a hereditary disease that occurs frequently. We will explain each of these.

Hypertrophic Cardiomyopathy

This is a condition where the heart muscle thickens, preventing the heart from contracting properly. Because the heart becomes unable to pump blood effectively, symptoms such as difficulty breathing, pleural effusion, and ascites may occur. It is known that Ragdolls are prone to hypertrophic cardiomyopathy due to a genetic mutation. Symptoms such as lethargy, lack of playfulness, or becoming tired easily can appear even at a young age. There is also a risk of sudden death even if the cat appears asymptomatic. In hypertrophic cardiomyopathy, blood clots can form inside the heart and tend to lodge in the large arteries of the hind legs. This results in symptoms such as hind leg paralysis, coldness or cyanosis (purple discoloration) of the paw pads, and intense pain.

By the time symptoms of hypertrophic cardiomyopathy appear, the condition is quite severe. Hospitalization, including the use of an oxygen chamber, is required for intensive care. Unfortunately, even with intensive treatment, there is a high possibility of a fatal outcome. Once the condition stabilizes, it transitions to oral medication, but the disease cannot be cured and requires lifelong medication.

Hypertrophic cardiomyopathy cannot be prevented. Therefore, early detection and early treatment are essential. Regular health check-ups are important.

Urolithiasis

While cats generally have a high possibility of developing urinary tract diseases such as urolithiasis, it is known that Ragdolls are somewhat more susceptible. Urolithiasis involves the formation of stones in the urinary tract, which are primarily composed of struvite or calcium oxalate. Struvite stones can be dissolved with a specialized therapeutic diet, but calcium oxalate stones cannot be treated through diet and require surgical removal. It is said that Ragdolls have a slight tendency to develop calcium oxalate stones. Symptoms of urolithiasis include frequent urination, going to the litter box repeatedly without being able to urinate, meowing loudly while urinating, blood in the urine, vomiting, and loss of appetite. If urolithiasis occurs and urine output stops, kidney function can decline within hours, becoming life-threatening. Therefore, it is necessary to see a veterinarian immediately.

Urolithiasis can be prevented to some extent. Feeding human food or excessive treats can increase the mineral content in the urine, leading to stone formation. Stick to feeding only cat food. Insufficient water intake also increases the risk. Ensure fresh water is always available. Obesity also increases the risk of urolithiasis, so it is important to manage their diet and prevent them from becoming overweight.

If diagnosed with urolithiasis, surgery might be necessary. Also, since urolithiasis can recur, continuing a therapeutic diet for urinary health is vital. Please note that over-the-counter urinary health foods are not designed for calcium oxalate, so you must use the therapeutic diet prescribed by your veterinarian. Regular check-ups are also required.

Trichobezoar (Hairballs)

Because Ragdolls have semi-long hair, they swallow a significant amount of fur while grooming. If only a small amount is swallowed, it is excreted in the feces, but larger amounts can form hairballs in the digestive tract, which can sometimes cause a blockage. Symptoms include vomiting, constipation, and loss of appetite.

Hairballs can be prevented through daily grooming. For Ragdolls, brush them at least twice a day to remove excess fur. Brush them frequently during shedding season. If the issue recurs, hairball prevention supplements may be used.

Summary

Due to their personality, Ragdolls are popular among first-time cat owners and those who already have other cats. While Ragdolls are prone to hypertrophic cardiomyopathy, urolithiasis, and hairballs, urolithiasis and hairballs can be prevented to some extent. Brushing is essential to keep their coat beautiful. Also, by being mindful of their diet, it is possible to prevent urolithiasis. Furthermore, ensure they have regular health check-ups and stay mindful of their health condition.
