How many calories does a British Shorthair need per day?

Most neutered adult British Shorthairs with low activity need approximately 190-430 kcal/day depending on body weight, with smaller females toward the lower end and larger males toward the upper. Use your cat's current weight and a low-activity multiplier (1.2-1.4) applied to RER as your starting point.

Why does my British Shorthair keep gaining weight even on normal portions?

The most common reason is that "normal portions" are calibrated for an average-activity cat, not the low-activity British Shorthair. Bag feeding guides typically overestimate needs for this breed. Recalculate using an RER-based formula with a low-activity multiplier and adjust based on monthly weigh-ins and body condition.

Should I feed my British Shorthair less after neutering?

Yes -- neutering reduces calorie requirements by roughly 15-30%. Adjust portions downward at the time of the procedure rather than waiting for weight gain to appear. Monitor body condition over the following 2-3 months and make further adjustments if needed.

Can I rely on the feeding guide on my cat food bag?

Use it as a rough starting point only. Bag guides tend to be calibrated for moderately active, often intact adults and frequently overestimate needs for low-activity neutered cats like the British Shorthair. An RER-based calculation adjusted to body condition gives a more accurate individualized target.
