I've just been through the same with Leo. Poops were fine, but he just wasn't eating. This lasted at least a week, and he's only just totally back to normal 2 weeks later. Treatment wise, we just did the usual...metaclop, zantac, metacam and sub-cut fluids. In the end the vet put him on baytril just in case it was due to some sort of infection.
Sending lots of vibes for both Rhia and Dylan x
