Well, I'm really confused now... Luna did it again, yesterday in the evening when she came onto my lap. Today, I noticed the same in Lily, but only once. So maybe it's nothing serious after all...? Still, it doesn't look skin-related to me.

And no, Luna is not on some kind of medication. I changed her diet to Hill's s/d a while ago to dissolve her struvite crystals. But she's been on that diet before in the past. And in her last blood test, potassium was fine.

Right now she's in my lap again and the twitching happens every couple of seconds, down to her legs and paws... Strangly enough, it seems to stop when I'm petting her.

Thanks for keeping Luna in your thoughts.
