Pet Calculators

Practical tools for picking the right size and the right amount, built from the measurements and pack sizes of the products we actually stock. We have 2 calculators, with more on the way.

Cat Litter Calculator

Work out how much litter a month your trays get through, and which pack size suits you. Covers full changes; topping up adds to it.

Dog Harness Size Calculator

Enter your dog’s chest and neck measurements and get the harness size that fits, with the measurement ranges we actually stock.
