If you feed your cat treats and snacks, please note they should not form more than 10% of the
whole diet’s calorie content. This means at least 90% of calorie contribution should come
from the complete cat food, and up to 10% from treats.
Pet owners are advised to use accurate kitchen scales to weight the food to the exact
amount recommended by the manufacturer or their vet. Feeding based on volume or estimating the
amount of food is subject to error.
Using the feeding guidelines and this calculator as a starting point, each individual cat
should be fed to their ideal body condition score. PFMA body condition charts can be found on
Regular weighing of the animal and adjusting their food to their need based on weight gain/loss,
by a veterinary professional, is also critical.
