In early 2020, she was starting to get snitty when Kira initiated play, and one day it occurred to me it might be her hips. So I started her on Cosequin for Cats, and lo and behold - she and Kira started playing again! So that's been almost 3 years. I'd say it helped.

I'll keep her on the Cosequin, of course. But as she keeps getting older, it's not surprising that it's not enough on its own.
