The maths behind it

This tool uses Each body condition point above 5 represents roughly 10% over ideal weight. Safe loss is about 1% of ideal body weight per week. Every intermediate value is shown on screen, so the result can be checked by hand.

Never crash-diet a cat. Cats that lose weight too quickly can develop hepatic lipidosis, a genuinely life-threatening liver condition, so feline weight loss needs a vet-supervised plan.
