Snowshoe cat care: PKD testing, grooming and play

Very little health research has been published on the Snowshoe specifically. The one condition the UK's Governing Council of the Cat Fancy reports in the breed is polycystic kidney disease, which has a DNA test and can be found on ultrasound. The breed's Siamese ancestry raises a question, so far unstudied, about familial amyloidosis. Day-to-day care is simple: a short single coat, plenty of interactive play and measured portions.

Where the breed comes from

According to the Governing Council of the Cat Fancy (GCCF), the Snowshoe dates to the early 1960s, when Dorothy Hinds-Daugherty, a breeder in Philadelphia, found three kittens with four white feet in a Siamese litter. She bred them to a domestic cat with tuxedo markings, and the white inverted "V" on the face followed. The Fédération Internationale Féline describes the crosses as seal point Siamese with bicolor American Shorthairs, and it has recognized the breed since 2004.

The result is a medium-sized, muscular cat with blue eyes, Siamese-style colored points and white trim. The GCCF gives a weight of about 9 to 12 pounds (4 to 5.5 kg) for males and 7 to 10 pounds (3 to 4.5 kg) for females, some of whom are as large as males. Kittens are born completely white. The points start to show within a few weeks and darken as the cat grows, and no two cats have quite the same white markings.

Its coat is a single layer with no undercoat. The GCCF notes that it needs no special grooming. A weekly brush or rubber mitt is enough to remove loose hair. The GCCF also points out that a Snowshoe which stops grooming itself is usually unwell or stressed, and that deserves a check.

Polycystic kidney disease

Polycystic kidney disease (PKD) has occurred in Snowshoes, according to the GCCF. In PKD, fluid-filled cysts form in the kidneys and slowly enlarge, crowding out working tissue. The best-known form is linked to a variant in the PKD1 gene, which a DNA test can detect.

A follow-up of 300 cats carrying the PKD1 variant in Japan shows what the disease does over a lifetime. Most cats lived well into adulthood, with 95% alive at five years. Survival dropped sharply from six to seven years of age, though, and only 61% were alive at ten. About one cat in six developed uremia, the build-up of waste products that comes with kidney failure. The authors recommend frequent checks from a young age in affected cats.

A cat with PKD or chronic kidney disease is often moved onto a renal diet as the disease progresses. That decision belongs with the vet and the blood results, not with the breed label. Keeping any cat well hydrated, with wet food and several water bowls, is sensible in either case.

The Siamese side

Siamese and Oriental cats carry a familial form of amyloidosis, in which an abnormal protein builds up in organs, especially the liver and thyroid gland. In a genetic study of affected Oriental Shorthair families, the authors describe the disease as fatal, with signs usually appearing between one and seven years of age. In the cats examined after death the liver had become fragile and bled into the abdomen. Whether the Snowshoe, which was developed partly from American Shorthair lines, carries a meaningful share of this risk is not something any published study has examined.

The practical point is to treat sudden weakness, pale gums, a swollen belly or collapse in a young adult Snowshoe as an emergency, and to mention the breed's Siamese background if a vet is investigating liver problems or unexplained weight loss.

Teeth

Gum disease and tooth resorption are common in cats of every breed, and there is no published evidence that Snowshoes are more affected. Signs are easy to miss: red gum edges, bad breath, drooling, chewing on one side or dropping food. Daily brushing with a cat toothpaste is the most effective home care. Introduce it slowly, first letting the cat lick the paste, then rubbing the gums with a finger, then using a small brush. The Veterinary Oral Health Council lists cat diets, treats and water additives that have passed its plaque or tartar trials.

Temperament and activity

The GCCF describes Snowshoes as inquisitive, active and intelligent, hard to unsettle, and generally talkers with a soft, melodic voice. They often learn to play fetch, enjoy wand toys and climbing frames, and tend to form a main bond with one person while staying friendly with others. The registry adds that most fit well into homes with several cats, but some prefer to be the only one. FIFe also notes that they are compatible with children and other pets.

An active, people-focused cat that spends long days alone can become bored. Two or three short play sessions a day, a climbing tree near a window and food puzzles for part of the ration give it an outlet and help keep weight down. Any sudden change in voice, appetite or litter box habits is more likely to mean pain or illness than a personality quirk, and needs a vet check.

Food, water and portions

Snowshoes have no breed-specific nutrient requirements, and a complete and balanced cat food for the right life stage covers them. The Merck Veterinary Manual lists taurine, vitamin A and arachidonic acid among the nutrients cats must get from food, which is why a cat should not be fed dog food or an unbalanced home-made diet. Merck also notes that cats often drink little, and that several water sources encourage drinking.

Energy needs start from the resting energy requirement (RER), 70 times body weight in kilograms raised to the power 0.75. A neutered adult cat needs about 1.2 times RER, an intact adult 1.4 times and a cat prone to weight gain 1.0 times. Rounded to the nearest 5 kcal:

Merck stresses that these are starting points, and a cat may need 30% more or less. Measured meals, two to four a day, make intake easier to track than a bowl that is always full. A mix of wet and dry food suits many cats and adds water. Judge condition by touch as well as by eye: the ribs should be easy to feel under a thin covering, with a visible waist behind them. Weigh an adult cat every month or two, and treat unexplained weight loss as a reason for a vet visit, given the kidney risk above.
