Quintus is doing really well and hasn't seen a drop of insulin since 1.1.18 -- and it really was a drop. His numbers are good so far. I went to the vet for a check-up and everything seems fine. There is just one thing I'm concerned about: is a kind of digestive (?) spasm he does when he's resting. It's pretty systematic (if I want to see it, I watch a while, and see it). Sometimes it's more marked than others. Sometimes it seems absent (but I need to check that this week-end when I can watch him more). It doesn't seem particularly painful (showed video to the vet), but I'm guessing at least uncomfortable. He also gets lower back "skin spasms". Two independent things? Something neurological? Vet says it doesn't seem very worrisome and complicated to investigate/treat at this stage. You can see the "skin spasm" here: https://photos.app.goo.gl/eyFUjfzs4guZ3AAx2 (I know about FHS, as it was a suspected diagnosis at some point for my deceased Tounsi) And the "digestive" one: https://photos.app.goo.gl/t5n5n1yBvBLOYC5n1 There are other videos in his photo album (scroll to the bottom for the latest). I've tried to figure out if it was linked to when he was eating, as we changed food after the FD diagnosis, or taking his meds. Initially I thought it was post-food or post-meds. I tried being careful to give his meds after food and not before. Still happened. I tried removing DM wet food, wondering if he was having trouble with that -- still there. My next trial is to remove m/d kibble and see what happens. He is on carbimazole (since October), onsior (since forever), fortekor (since forever), and amlodipin (a couple of years). My next best idea is to book another session with the vet osteopath. Osteopaths are sometimes better with subclinical stuff. She also gets 45 minutes with a mostly resting cat, so she's going to witness it directly. She might have ideas or be able to tell me more precisely what it seems to be. And I'm also turning to you: is this something you've come upon? Any ideas? Worrisome, or not so much? Thanks in advance!
