Actually she's doesn't seem that bad - she's still as active and happy as ever.
Had to take her to the vet's last night as she had blood in her urine. She had an x-ray and thorough examination and vet says she has some slight inflammation. She had a shot of antibiotics and we have some more antibiotics to stick in her water each day.
Just wondering if anyone else had a similar issue with a rabbit and how long did it take to clear up?
