Cat Supplements

Cat supplements from a licensed Canadian pharmacy. Urinary and kidney support, joint and mobility formulas, liver support, hairball and digestive aids, calming products and daily multivitamins - dispensed from our accredited pharmacy in Orleans, Ontario and shipped across Canada. Cats are not small dogs, so we stock cat-specific dosing and flavours rather than asking you to split a canine product.

How to compare cat supplements

Urinary and kidney: compare phosphate binder content, omega-3 (EPA/DHA), and whether the product is a powder to mix into food or a capsule. Palatability decides whether a cat actually takes it.
Joint: glucosamine, chondroitin and green-lipped mussel are the common actives. Cat doses are much smaller than dog doses - check the label rather than estimating.
Digestive and hairball: probiotics list CFU count and strains; hairball products rely on fibre or petrolatum-based lubricants. They do different jobs.
Calming: alpha-casozepine, L-theanine and pheromone products work differently and can be combined. Ask us which combination fits the trigger.

Talk to a pharmacist before you start

Speak with us first if your cat has chronic kidney disease, hyperthyroidism, diabetes, or takes a prescription medication such as methimazole, benazepril or insulin. Supplements are not a substitute for veterinary care or for a prescribed medication.

Questions about a specific product or dose? Call the pharmacy at 613-824-3111, or see how our pet prescription and compounding service works - including tuna-flavoured compounded medications for cats that will not take a tablet. Also browse dog supplements or the full pet supplements range.
