How Much to Feed a Russian Blue
Russian Blues are naturally lean and muscular, which can trick owners into overfeeding. Their elegant build doesn't mean they need extra calories—it means they thrive on quality protein in modest portions. This guide will help you feed your Russian Blue to maintain that distinctive sleek silhouette while supporting their active, athletic nature.

Veterinary RER/MER formula — daily calories, grams and cups.
RER 184 kcal × 1.2 (adult, neutered/spayed) = 221 kcal, at 380 kcal/100g. Estimates for healthy pets — always confirm with your veterinarian.
The most common mistake Russian Blue owners make is feeding portions designed for average cats. Russian Blues have a deceptively efficient metabolism; their smaller frame and high activity level mean they need less food than comparably-aged cats of other breeds. Many owners see their lean build and assume underfed-ness, then gradually increase portions until the cat loses its signature elegance. The calculator above provides a starting point based on your individual cat's weight, but watch your Russian Blue's body condition over several weeks before adjusting upward.
Protein quality matters more for Russian Blues than meal frequency. These cats have a natural affinity for lean muscle development, which a high-protein diet supports without requiring excess calories. Look for foods listing named meat sources (chicken, fish, turkey) in the first ingredients rather than grain fillers or meat by-products. Russian Blues are often enthusiastic eaters, so portion control at mealtimes is more effective than leaving food down all day—it gives you precise feeding accountability and prevents mindless grazing that adds unnecessary weight.
Monitor your Russian Blue's weight and muscle definition monthly. You should easily feel their ribs without pressing hard, and they should have a visible waist when viewed from above. A cat that looked properly lean at four pounds may look soft at six, even though two pounds seems minor. Russian Blues' short, dense coat makes weight gain obvious once it happens, so catching gradual creep early prevents the metabolic slowdown that makes weight loss harder later. Adjust portions based on body condition rather than age or random recommendations.
Frequently asked questions
How much food should a Russian Blue eat per day?
A typical adult Russian Blue weighing 8 lbs needs about 221 kcal per day (adult, neutered/spayed), which is roughly 58 grams — about 0.6 cups — of standard dry food, split into 2 meals.
How is the Russian Blue's daily portion calculated?
We use the standard veterinary formula: Resting Energy Requirement (RER) = 70 × (weight in kg)^0.75, then multiply by a life-stage factor. For a 3.6 kg Russian Blue, RER is 184 kcal, and the adult, neutered/spayed factor of 1.2 gives 221 kcal per day.
Should I free-feed my Russian Blue or use scheduled meals?
Scheduled meals are better for Russian Blues. Free-feeding encourages grazing, and these cats can easily overeat when food is constantly available, despite their active nature. Two meals per day at set times gives you control over portions and makes it easy to spot appetite changes that signal health issues.
Can I give my Russian Blue treats without affecting their weight?
Yes, but treats should be occasional and tiny. Russian Blues' small size means even small treats represent a larger calorie percentage of their daily intake than for bigger cats. Reserve treats for training or bonding rather than routine snacking, and stick to single pieces or very small portions.
What does a healthy Russian Blue body actually look like?
A healthy Russian Blue should have visible ribs and spine (palpable, not protruding), a tucked waist when viewed from the side, and a slight abdominal tuck. Their muscular legs should be lean but firm. The breed's short coat makes body condition very visible, so if you're unsure, comparing your cat to breed photos is more useful than comparing to other average cats.
