Thankyou everyone. I looked after Dusty for four years until I moved to college, then I had to pass the responsibility to someone else. I don't blame them for having her put down, she was so very ill and I know that. I nursed her alone for the last year. 6 isn't a bad age for a pedigree rabbit, I don't think. She was an outdoor rabbit too, so 6 is quite good...
My dear Bandit is 4 in March, so she's doing well. She's our oldest Smoke-Pearl now.
