Ordered the Seraquin for our 17 year old girl, prior to taking these she was in real discomfort with her back legs and she would cry in pain if you stroked her back. She is a fussy cat but takes these like treats and after a couple of days of taking these supplements the transformation in her was amazing. She is walking better and no longer cries when stroked. I just wish we came across these earlier! I would definitely recommend trying these if your furry friend is showing signs of arthritis. Mr Pets was great, sent my order very quickly, and I would definitely recommend them and I will be using them again, in fact I am just about to place another order :)
