My senior cat shows no arthritis. Should I still give him glucosamine?

You should get glucosamine and SAMe tablets - they are natural supplements with scientific proof that they do something good for the joints. You should be able to get these products over-the-counter at pet shops or at the vets.

At his age, he likely has some arthritis. I suggest you get him started on a joint supplement. https://worldtails.securevetsource.com/itemView/view/198944_HomeDelivery.pml?productId=120626 Give it a good 4-6 weeks to see if it helps him. If not, then please post again and we'll see if we can give you some more suggestions.

No, I would not give this to Dixie. It may be the incorrect dose for her, and you can accidentally do harm to her by giving her it. I would have her seen by a vet first thing Monday. Until then, I would rest her and keep her as quiet as possible. You can give her glucosamine and chondrotin sulfate supplements which help with joint problems such as arthritis.

This appears to be a good supplement. Glucosamine and fish oils are beneficial in many dogs that may be prone to developing arthritis or other bony disorders as they get older. However, scientific data on these types of supplements is lacking. Similar to humans, they might help and don't hurt anything. If you want to give them to Jesse, that is fine, but I do not routinely recommend these types of supplements in young-ish dogs.

Yes, this is fine to give to your cat. Just be sure to get the one formulated for cats. I do recommend taking her into a vet, however, as she may be painful. Cats can be stoic about pain, and can be quite good at hiding it. If she is in pain, she would benefit from pain medications which the vet can prescribe. Unfortunately you cannot give her any human pain medications, as many are toxic to cats and are fatal if given. I would have her seen by a vet in the next day or two. Good luck, I hope this helps!

Many cats show signs of osteoarthritis on radiographs as seniors even when they don't seem to be obviously painful. Since this is a recent change I'd recommend seeing your vet for a physical exam. If they agree that your cat may have arthritis they might recommend a joint supplement like Dasuquin or a trial of pain medication to see if it helps with mobility.

Most likely this is arthritis. If he isn't limping then this is aa good indicator that it isn't causing too much pain yet. You can try over the counter joint supplements like Cosequin to help replenish fluid in the joint and also to help slow down the progression of arthritis. If he develops pain or limping then it is best to have the limb radiographed to get a better idea of what is happening internally, and also to get a prescription for stronger medications to help with pain.
