Today my back up vet (who helps run these projects) told me that through the images taken during their research on Spike (after he'd been humanely euthanized), vets have discovered a major artery running alongside a beardie's ribs that makes the perfect injection site for a catheterizing. Its revolutionary! No vets had known it was there before the new imaging data.
I'm so proud. And grateful. Spike was a tough rescue, but his life is leaving a legacy that will help many future bearded dragons. And that makes my heart happy.
