Russian Blue: a robust breed, but watch weight and urinary tract

The Russian Blue is one of the healthiest cat breeds: few specific hereditary diseases are attributed to it. That does not remove the need to watch the two big risks of any indoor cat, excess weight and urinary stones, all the more so as this calm, home-loving cat moves little. All our pointers are in the cat care and grooming section, with the full profile on the Russian Blue page.

Excess weight, the first enemy

A placid cat, the Russian Blue easily gains weight indoors, and obesity opens the door to several diseases. A study by Scarlett and Donoghue, published in 1998 in the JAVMA, established that an overweight cat has a markedly higher risk of diabetes, skin disorders and urinary conditions (study on Google Scholar). Precise portioning and encouraging play are the best prevention.

Urinary stones and diet

Urinary stones are a frequent feline emergency, partly diet-related. A study by Lekcharoensuk and colleagues, published in 2001 in the JAVMA, showed that dietary factors, notably the low moisture of dry food, strongly influence the risk of oxalate and struvite stones (study on Google Scholar). Promoting hydration and a suitable diet lowers this risk.

And its low-allergen reputation?

Like the Siberian, the Russian Blue is sometimes billed as better tolerated by allergy sufferers. Here too, variability is individual: a study by Bastien, Gardner and Satyaraj, published in 2019 in the Journal of Feline Medicine and Surgery, showed very large differences in Fel d 1 production from one cat to another (study on Google Scholar). There is no truly "hypoallergenic" breed.

What care budget to plan

A healthy breed, the Russian Blue costs mainly in prevention and routine care, barring accident or urinary disease. Our guide to pet insurance for cats helps you decide, and our page on insuring a Russian Blue spells out the useful cover.
