Turns out she has a mild chest infection. I got a scrip for some meds and spent about 30 mins waiting for her "bag of help" at Tesco's chesmist. This photo was taken as we waited for her drugs, she not a happy or well bunny.
Still, the doc said as soon as her jollop was administered, she should feel much better.
It's been about an hour now and she's cooled down and doesn't seem so listless.
