British Shorthairs are built like little teddy bears — dense coat, round face, solid frame — and that charm hides a problem: the breed gains weight extraordinarily easily. A neutered indoor British Shorthair with a leisurely attitude to exercise can drift from “cuddly” to genuinely overweight on what looks like a perfectly normal feeding routine, and treats handed out on top of meals are usually where the extra calories sneak in.
That is exactly why owners search for the best cat treats for cats on a diet for British Shorthairs. The good news is that going on a diet does not have to mean the end of treat time. What it means is choosing treats with a known, low calorie count per piece — ideally around 2 kcal or less — and budgeting them properly, the way you’d budget any other part of the day’s food.
We compared the leading low-calorie options on calories per treat, ingredient quality, portion control and how satisfying cats actually find them, and narrowed it down to these five.
First, the Maths: How Many Treats Can a Dieting British Shorthair Have?
A British Shorthair who should weigh about 5 kg typically needs somewhere in the region of 250–280 kcal a day to maintain that weight as a neutered indoor cat — your vet will pin down the exact figure for your cat. The widely used rule of thumb is that treats should supply no more than 10% of daily calories. On 260 kcal a day, that is a treat budget of roughly 26 kcal.
At around 2 kcal per treat, 26 kcal buys you about 12 treats a day — more than enough for training, bonding and a bedtime ritual. But two things matter. First, those treat calories must come out of the food bowl, not go on top of it: if you feed the full day’s meals plus 26 kcal of treats, there is no calorie deficit and no weight loss. Second, if your vet has set a reduced daily target for active weight loss — often nearer 200–220 kcal — the 10% share shrinks to about 20 kcal, or roughly 10 treats. Small numbers, honestly counted, are what make a cat diet work.

What to Look for in a Treat for a Cat on a Diet
- A printed calorie count per treat: This is the single most important detail. Look for treats at roughly 2 kcal per piece or less, with the figure stated on the label — if a brand won’t tell you the calories, assume they’re not low.
- Small, uniform pieces: Even sizing makes counting honest. Oversized or variable treats make it far too easy to overfeed “just a few.”
- Real protein first: British Shorthairs are muscular cats; on reduced calories they need protein to keep muscle while losing fat. Meat or fish as the first ingredient beats cereal-heavy biscuits.
- Nothing your cat will gorge on unnoticed: Resealable tubs and bags matter in a house with a determined, food-motivated cat. Treats stored where a British Shorthair can self-serve will be self-served.
- A format that stretches the experience: Flakes, lickable textures and puzzle-feeder-friendly pieces make a small calorie allowance feel like a big event — especially useful for a breed that notices every reduction.
- Part of the plan, not an extra: Whatever you choose, weigh out the day’s treat allowance in the morning and take the same calories off the meals. When the pot is empty, treat time is over.
1. Feline Greenies Dental Treats, Oven Roasted Chicken — Best Overall
Greenies are the pick we’d hand most dieting British Shorthairs first, because they solve two problems at once. Each crunchy treat contains less than 2 calories, and the texture and shape are designed to help clean teeth and reduce tartar build-up as the cat chews — dental care being something indoor cats on measured diets often need more of, not less. Greenies describes them as the #1 vet-recommended feline dental treat, and the formula is nutritionally complete and balanced for adult cats, with added vitamins, minerals and taurine and no artificial flavours or preservatives.
Feeding guidance is clearly printed — the label suggests up to 8 treats twice a day for a 10 lb cat alongside its regular diet — but on a weight-loss plan you should treat that as a ceiling for maintenance, not a target: count them against your cat’s 10% budget (around 10–12 a day for most dieting British Shorthairs) and reduce the meals to match.
Pros: Under 2 kcal per treat; dental benefit built in; complete and balanced formula; big resealable tub keeps pieces fresh; widely consistent sizing for honest counting.
Cons: Contains grains (chicken meal, ground wheat, brewers rice), so not for grain-sensitive cats; the larger tub encourages casual handful-giving if you’re not disciplined.
Best for: Most British Shorthairs on a diet — low calorie, portion-friendly, and good for teeth at the same time.
2. Wellness Kittles, Salmon & Cranberries — Best Natural, Grain-Free
Wellness Kittles are crunchy little bites made with real salmon as a leading ingredient, plus cranberries and blueberries, and each treat comes in at under 2 calories. The recipe is grain-free and made with all-natural ingredients — no meat by-products, wheat, corn, soy, or artificial colours, flavours or preservatives — and the crunchy texture gives a modest teeth-cleaning effect as your cat crunches.
The 2 oz bag sounds small, but it holds well over 100 treats, which at a dieting cat’s rate of about ten a day is a sensible fortnight’s supply — and a small bag is quietly helpful for portion discipline, because there’s less sitting in the cupboard tempting everyone to be generous.
Pros: Under 2 kcal per treat; grain-free with real salmon first; clean, simple ingredient list; crunchy texture; small bag suits controlled treating.
Cons: Cost per treat is higher than the big mainstream tubs; fish flavour won’t suit every cat; bag is not as gnaw-proof as a rigid tub.
Best for: Owners who want a natural, grain-free recipe with a clearly stated low calorie count.
3. PureBites Chicken Breast Freeze-Dried Treats — Best Single Ingredient
PureBites strips the idea back to basics: one ingredient — 100% pure chicken breast, sourced and freeze-dried raw in the USA — and an average of just 2 calories per treat. There are no colours, fillers or sweeteners, which makes these an easy choice for cats on restricted diets or with ingredient sensitivities, and the high protein content suits a muscular breed that needs to lose fat, not muscle.
Because the pieces are freeze-dried, you can break a larger chunk into two or three smaller rewards, stretching one 2 kcal piece across a whole training moment. The 2.3 oz bag contains roughly 175 treats, and the pieces also crumble beautifully over a measured meal if your British Shorthair is unimpressed by a reduced portion.
Pros: Single ingredient; only ~2 kcal per average treat; high protein; pieces can be broken smaller to stretch the allowance; nothing artificial added.
Cons: Piece size varies, so “average” calories need a little judgement; crumbly texture leaves dust at the bottom of the bag; premium price for the weight.
Best for: Cats with sensitivities, fussy eaters, and owners who want total ingredient transparency.
4. Cat-Man-Doo Extra Large Dried Bonito Flakes — Best for Tiny, Frequent Rewards
Bonito flakes solve the dieting cat’s biggest emotional problem: the feeling that treats have become rare. These flakes are a single-ingredient, human-grade dried fish with nothing added — high in protein, low in fat, and containing natural taurine — at roughly 90 calories per ounce. That sounds like a lot until you realise a generous pinch of flakes weighs almost nothing: a few flakes offered one at a time add up to only a handful of calories, yet your cat experiences a long, exciting string of rewards.
They’re equally useful sprinkled sparingly over a measured portion of diet food to make a smaller meal smell like a feast, which can be the difference between a British Shorthair accepting the new routine and staging a protest. Feed flakes as a treat or topper, not as a meal replacement, and store the bag sealed — the aroma that drives cats wild will also draw them to an open bag.
Pros: Feather-light, so per-reward calories are tiny; single ingredient, high protein, natural taurine; superb for training and food topping; a little goes a very long way.
Cons: No per-piece calorie count — you have to think in pinches and grams; strong fishy smell; flakes can be messy around the bowl.
Best for: Training, clicker work, and cats who need frequent small rewards without denting the calorie budget.
5. Temptations Classic Crunchy and Soft, Tasty Chicken — Best Budget Pick for Fussy Cats
Temptations are the treats cats famously come running for at the shake of the tub, and the Classic recipe keeps each crunchy-outside, soft-inside piece at under 2 calories. They’re 100% nutritionally complete and balanced for adult maintenance, come in a large resealable stay-fresh tub, and the brand’s own guidance of up to 15 treats per 10 lb of body weight sits comfortably inside a sensible 10% treat budget for a cat at maintenance — on a weight-loss plan, simply count out fewer and trim the meals.
The honest trade-off is the ingredient list: these are a mainstream treat built for palatability, with chicken by-product meal and ground corn in the mix, so owners who prioritise whole-food ingredients will prefer the Kittles or PureBites above. But for a stubborn British Shorthair who turns his nose up at “virtuous” treats, the best low-calorie treat is the one he’ll actually eat at 2 kcal rather than the 8 kcal artisanal biscuit someone slips him out of guilt.
Pros: Under 2 kcal per treat; famously irresistible to fussy cats; complete and balanced; big tub is excellent value; resealable tub keeps paws out.
Cons: Mainstream ingredient profile (by-product meal, corn); the shake-the-tub ritual can train the whole household into over-treating; easy to pour rather than count.
Best for: Fussy cats and tighter budgets — reliable, countable, and very hard for a cat to refuse.
Making a Small Allowance Feel Big: Format Tricks and Play
Scatter and hunt: Ten 2 kcal treats tossed across a room or hidden in a cardboard forage box take ten minutes to “earn” — far more satisfying than the same treats from your hand in ten seconds. Freeze-dried pieces (PureBites) break into crumbs that flavour a whole bowl. Flakes (Cat-Man-Doo) turn one reward into twenty micro-rewards. And remember the most underused treat of all: play. Five minutes with a wand toy before the evening treat ritual burns calories, satisfies the hunt-chase-catch-eat sequence British Shorthairs are wired for, and often reduces the treat-begging that follows boredom. A puzzle feeder filled from the day’s measured meal allowance — not extra food — gives the same reward experience at zero additional calories.
Safety Notes: Weight Loss in Cats Must Be Slow
- Never crash-diet a cat. Cats — especially overweight ones — that eat far too little or stop eating can develop hepatic lipidosis (fatty liver disease), a serious and potentially life-threatening condition. Weight loss should be gradual: a common target is around 0.5–1% of body weight per week, which for a 5 kg cat is only about 25–50 g a week.
- Get a vet-set plan. If your British Shorthair is significantly overweight, is diabetic, or has any other health condition, agree the daily calorie target and rate of loss with your vet or vet nurse, and weigh monthly on the same scales. Sudden appetite loss in an overweight cat is a reason to call the vet promptly, not a dieting success.
- Treats come out of the bowl. Every treat calorie must be subtracted from the day’s meals. Treats fed “on top” are the most common reason cat diets fail.
- One treat-giver rule. In multi-person households, use a daily treat pot counted out in the morning. If everyone feeds treats independently, nobody is feeding 10% — you’re each feeding 10%.
- Watch the cat, not just the scales. Energy, coat condition and litter-tray habits should stay normal. Vomiting, lethargy, hiding or refusing food for more than a day on a new diet all warrant a vet call.
Frequently Asked Questions
How many treats can my British Shorthair have per day on a diet?
Work from the 10% rule: treats should be no more than a tenth of daily calories. For a British Shorthair who should weigh about 5 kg, that’s roughly 20–26 kcal of treats a day depending on whether they’re maintaining or actively losing — about 10–12 treats at 2 kcal each — and those calories must be taken off their meals.
Are dental treats like Greenies OK for a cat that’s losing weight?
Yes, provided you count them. Feline Greenies are under 2 kcal per treat, so they fit comfortably in a treat budget; just don’t follow the generous maintenance feeding guide on the tub and feed full meals on top.
Can I just cut my cat’s food down sharply to speed things up?
No. Rapid restriction is genuinely dangerous in cats because of the risk of hepatic lipidosis. Aim for slow, steady loss of roughly 0.5–1% of body weight per week, and see your vet if your cat stops eating or loses weight much faster than planned.
My cat begs constantly — will low-calorie treats really help?
They help with the maths, but the behaviour side matters too: fixed treat times, a counted daily pot, puzzle feeders stocked from the meal allowance, and a play session before treats all reduce begging far better than giving in. Feeding a treat every time a British Shorthair asks trains him to ask constantly.
What about lickable tube treats?
They can work, but read the label carefully — many lickable treats carry several times the calories of a 2 kcal crunchy treat per tube, so one tube may use up half the day’s treat budget. They’re best as an occasional high-value reward (vet visits, grooming) rather than a daily habit for a dieting cat.
Our Verdict
For most British Shorthairs on a diet, start with Feline Greenies Dental Treats — under 2 kcal a piece, easy to count, and they look after the teeth while the waistline shrinks. Choose Wellness Kittles for a natural grain-free recipe, PureBites Chicken Breast for single-ingredient purity and breakable pieces, Cat-Man-Doo Bonito Flakes when you need lots of tiny rewards for training, and Temptations Classic for fussy cats and excellent value. Whichever you pick, count out the day’s allowance each morning, take it out of the food bowl, add a daily play session — and let the weight come off slowly, the safe way.
