Its something most of us wouldn't think about. You assume its natural for a rabbit to be outside. I am pretty sure this is what happened to Sunshine years ago. He was an outdoor rabbit back then. It was a scorching day but he was in the shade with Nancy. I had to rush him to the vets. Took a few days for him to recover. Back then I had no idea what was wrong with him. The vets, not my usual vets could find nothing wrong. It was probably heatstroke.
