Protexin Veterinary Dasuquin Advanced Joint Supplement for Cats, with ASU, Glucosamine HCl and Chondroitin for Joint Care and Support - 60 Sprinkle Capsules, Add to Food

So this is the go to medicine for cats with joint pain, I ordered first batch May 2023 and followed the following guidance as per vet, first 60 days 1 per day, then after 1 per 3 days. First bottle that came expired on 9/2023, which is fine as it ran out end of June. Second bottle had the same expiry 9/2023, which is unacceptable as the general guidance is for 30 days 1 pill, then 1 pill every other day, so two months was NOT acceptable.I am only writing a review as I have another order coming up and I hope the expiry is checked and old pill pill bottles returned / thrown away.As for the effect, well the is the issue. Arthritis cant be cured nor can it be reversed with drugs, however it can be slowed down. Now there is no way of me being able to tell if it is slowing down. My cat has always been on healthy food, healthy lifestyle and is very active since a kitten. The best i can do here is update IF new symptoms arise, for now she has mild very early stages of arthritis and aside from mild stiffness she isnt showing any major signs. Could that mean its working, no idea? Vet couldnt answer that either.EDIT: The expiry problem happened 3 times. Amazon insisted it was going to investigate but the problem persisted. Eventually I got new pill bottles with the others refunded but this was very annoying. Also still seeing no change.
