Selkirk Rex Care Guide — The Curly-Coated Teddy Bear

The Selkirk Rex looks like a cat that just walked through a cloud — a plush, curly-coated teddy bear with round eyes and an impossibly gentle demeanor. Unlike most curly-coated cat breeds, the Selkirk Rex is a medium-large cat weighing 3–7 kg, with a stocky, muscular build inherited from its Persian, British Shorthair, and Exotic Shorthair ancestry. That ancestry also means this breed carries specific health risks that responsible owners need to understand.

The Selkirk Rex Coat — Unlike Any Other Rex

The Selkirk Rex coat is genetically distinct from the Devon Rex and Cornish Rex. While those breeds carry recessive rex genes, the Selkirk Rex curl is caused by a dominant gene — meaning only one copy is needed for the curly phenotype to appear. This is why a Selkirk Rex crossed with a straight-coated cat can still produce curly kittens.

The coat comes in two varieties — longhair and shorthair — and both have loose, individual curls rather than tight waves. The whiskers are curly too, which is one of the breed's most charming features. The coat texture is plush and dense, sometimes compared to sheep's wool, and it goes through phases of curliness throughout the cat's life. Kittens are often born with tight curls that loosen around 8–16 weeks, then gradually tighten again as the cat matures.

Coat Care Essentials

• Bathing frequency: Every 4–6 weeks. The curly coat can trap oils more than straight coats, leading to a greasy feel if neglected.
• Drying: Air-dry or use a diffuser on low heat. Towel-scrunching preserves curl structure. Avoid high-heat blow-drying.
• Ear cleaning: Curly hair grows inside the ear canal, increasing wax buildup. Check and clean ears weekly.
• Shedding: Moderate. The curly coat traps shed hair, so loose fur tends to stay tangled in the coat rather than falling onto furniture — making regular grooming important to prevent matting.

Health Concerns — The Persian Heritage Factor

The Selkirk Rex was developed using Persian, British Shorthair, and Exotic Shorthair outcrosses. While this created the breed's beautiful, stocky build and plush coat, it also introduced several hereditary health conditions that owners must screen for:

PKD — The Most Important Test

Polycystic kidney disease is an autosomal dominant condition inherited from the breed's Persian ancestry. Affected cats develop fluid-filled cysts in the kidneys that grow over time, eventually leading to kidney failure. The disease is progressive and has no cure, but early detection through DNA testing and ultrasound allows for dietary management that can significantly slow progression. A PKD-positive cat should be fed a kidney-supportive diet — moderate protein, low phosphorus, and adequate hydration.

HCM Screening

Hypertrophic cardiomyopathy causes thickening of the heart muscle and is one of the most common heart conditions in cats. For Selkirk Rex cats, annual echocardiograms starting at one year of age are recommended. Early detection allows for medication that can manage symptoms and slow progression. Taurine supplementation through diet is important for heart health in all cats, but especially in breeds with HCM prevalence.

Temperament and Living with a Selkirk Rex

The Selkirk Rex is often described as a "teddy bear cat" — and the comparison goes beyond appearance. These cats are exceptionally gentle, patient, and affectionate. They tend to be less demanding than Siamese or Oriental breeds but more interactive than Persians. They enjoy being held, tolerate handling well, and are generally good with children and other pets.

Their energy level is moderate. Selkirk Rex cats enjoy play sessions but are equally happy lounging on a lap. They are not climbers or jumpers by nature — their stocky build makes them more ground-oriented. Interactive toys, puzzle feeders, and regular play sessions of 15–20 minutes twice daily are sufficient for most Selkirk Rex cats.

• Social needs: They do not do well left alone for long periods. Consider a companion cat if you work full-time outside the home.
• Vocalization: Quiet breed. They communicate with soft chirps and purrs rather than loud meowing.
• Adaptability: Good with change, making them suitable for apartments and multi-pet households.

Nutrition for the Selkirk Rex

As a medium-large breed (3–7 kg), the Selkirk Rex has moderate caloric needs — typically 200–350 calories per day depending on size, activity level, and whether the cat is sterilized. Their Persian ancestry means they can be prone to weight gain if overfed, and extra weight puts additional strain on joints already susceptible to hip dysplasia.

• Protein: At least 35–40% on a dry matter basis. High-quality animal protein supports the dense coat and muscular build.
• Omega-3 and omega-6: Essential for maintaining the curly coat's texture and preventing dry, brittle curls. Look for foods with fish oil or salmon as an ingredient.
• Biotin and zinc: Support coat health and curl quality from within.
• Joint support: Given the breed's predisposition to hip dysplasia, foods with glucosamine and chondroitin are beneficial, especially for cats over 5 years old.
• Hydration: Wet food or water fountains help protect kidney function — particularly important given PKD risk.

Hip Dysplasia in Cats — A Real but Underdiagnosed Problem

Hip dysplasia is commonly associated with dogs, but it occurs in cats too — and certain breeds, including the Selkirk Rex, Maine Coon, and Persian, have higher rates than the general feline population. In cats, symptoms are often subtle: reluctance to jump, stiffness after rest, or a slight waddle when walking. Many owners attribute these signs to the cat "slowing down" when the underlying cause is treatable joint disease.

Management strategies include:

• Weight management: The single most effective intervention. Every extra 500 g matters for a medium-sized cat's hip joints.
• Low-impact exercise: Encourage horizontal play (chasing toys along the floor) rather than vertical jumping.
• Warm resting areas: Heated beds can reduce stiffness, especially in older cats.
• Supplements: Glucosamine, chondroitin, and omega-3 fatty acids support joint health. Many veterinarians also recommend green-lipped mussel extract for cats with joint concerns.
