Russian Blue Feeding Guide

How much to feed an adult Russian Blue

Adult Russian Blues typically weigh between 3 kg and 5.5 kg (roughly 6.6–12 lb). Using the standard feline resting energy requirement formula (RER = 70 × body weight in kg^0.75), a 4 kg neutered adult Russian Blue has an RER of approximately 150–160 kcal/day, with a maintenance energy requirement (MER) of around 180–210 kcal/day depending on activity level. A moderately active 5 kg cat may need closer to 220–250 kcal/day.

In practical terms, most Russian Blues do well on roughly 50–75 g of a high-quality wet food per meal (two meals per day), or the calorie-equivalent in dry kibble per their food's packaging — typically around ⅓–½ cup of a 350–400 kcal/cup kibble split across two servings. Always check the specific caloric density of your chosen food rather than relying on generic cup measures, since formulas vary widely.

Two measured meals per day is strongly preferred over free feeding or a single large meal. Because Russian Blues are notorious for appearing hungry even shortly after eating, setting consistent mealtimes and refusing to top up the bowl between meals is essential. If your cat is persistently vocal between meals, increase the proportion of wet food (which has higher volume per calorie) rather than simply increasing portions.

Feeding through life stages

Kittens (up to 12 months) have much higher calorie needs per kilogram than adults — roughly 2–3 times the adult maintenance requirement during peak growth. A Russian Blue kitten should be offered a complete, kitten-formulated food ad libitum up to about 4 months, then transitioned to three measured meals per day from 4–6 months, and two meals from 6–12 months as growth slows.

At 12 months, transition to an adult formula. Russian Blues reach their full adult size around this age, and continuing to feed a kitten formula beyond this point can contribute to early weight gain. Senior cats (generally 11 years and older) may benefit from a senior formula with adjusted phosphorus levels and added joint support, particularly given this breed's risk of bladder stones and the importance of kidney health over a lifespan that can reach 15–20 years.

The Russian Blue's food-begging quirk — and what to do about it

A common misconception among Russian Blue owners is that a cat repeatedly seeking food must genuinely be underfed. In reality, Russian Blues are conditioned beggers: the breed is highly observant and quickly learns that vocalising or rubbing against owners produces food. This is a behavioural tendency, not a sign that portions are too small.

The best response is consistent structure. Feed at the same times each day, remove the bowl after 20–30 minutes, and avoid offering top-ups outside meal windows. Puzzle feeders or slow-feed bowls can extend mealtime engagement and provide mental stimulation without adding calories. If you are uncertain whether your cat's weight is appropriate, a body condition score assessment and a conversation with your vet is far more reliable than simply increasing portions in response to begging.

Wet food, dry food, or mixed?

Russian Blues benefit from including wet food in their diet, both for hydration and satiety. Because the breed is predisposed to bladder stones, adequate fluid intake supports urinary tract health. Wet food provides roughly 70–80% moisture compared to dry kibble's 8–10%, making it a meaningful contributor to daily water intake.

A mixed feeding approach — wet food at one or both meals, with a small amount of dry kibble — is a practical balance. If feeding exclusively dry, always ensure your Russian Blue has access to fresh water throughout the day, and consider a pet water fountain to encourage drinking. Always consult your veterinarian before making major dietary changes, particularly if your cat has a history of urinary issues.

Treats and extras

Treats should make up no more than 10% of total daily calories, per WSAVA and AAHA nutrition guidelines. For a 200 kcal/day Russian Blue, this means no more than 20 kcal from treats — roughly one or two small commercial cat treats. Given this breed's tendency toward obesity and bladder stones, high-sodium or very dense treats should be chosen sparingly.

Training treats are a good use of the treat budget — Russian Blues are intelligent and responsive to positive reinforcement, and small training sessions are also a source of mental stimulation. Count every treat, chew, or food-based reward as part of the daily calorie total to avoid creeping calorie surplus.
