Last night, Uri the Hamster died. He was in the hamster ball and managed to get out of the room before we could put the barrier across the door. We found him at the bottom of the stairs with a suspected broken back. We took him to an emergency 24 hour vet - she said it might be broken but she coundn't be sure without an x-ray (which would have been too expensive). She gave him an injection of steroids and painkillers so if his back was injured rather than broken, it would help him recover. We were told to take him to our usual vet in the morning. Sadly, he died shortly after getting him home.
