I bought my elderly cat some arthritis supplements from the vets as I figured she might need them. They were quite dear.
However, she doesn't like them and refuses to have anything to do with them 
I also caught her running around a few days ago, so I don't think her joints are actually bothering her.
These supplements are just sitting in the cupboard and I do have creaky knees, so do you think it would be reasonable for me to take them instead?
