Input (English): [header] How to give your cat a joint supplement [title] Determine if your cat needs a supplement. [step] It is okay, and probably even best, to give your cat a joint supplement before they show signs of pain or arthritis. Supplements will keep your cat's joints healthy and help slow the process of deterioration as they age. <sep> (A) [substeps] When you are giving the joint supplement, take at least two or three tablets at a time. Note that unless your cat's vet prescribed it, any pain or swelling over the prescribed amount should have subsided. (B) If your cat is showing signs of arthritis and you haven't been giving them supplements, keep in mind that they take about four to six weeks to work and increase your cat's mobility. Signs of arthritis can be difficult to spot since arthritis shows itself differently in cats. (C) Your veterinarian will recommend your cat's preferred supplement, and follow its directions carefully. [substeps] When your cat is turning its joints inward, their joints will begin to latch. (D) You can either purchase a joint supplement at your local veterinary office or make your own through a special veterinary shop. [substeps] If your cat suffers from an ear infection or greatly needs a joint supplement, they should see a vet.
