Just an update on my Falcore !
I just called the Vet and she has explained that his outlook is guarded at the moment so he will be kept in overnight to be monitored. He has been force fed with a special diet to get him to poo so they can investigate further but so far he is refusing to go to the bathroom (he is very shy). She said that these guys can cause themselves further injury if they don't eat or drink enough that can cause kidney damage so I am hoping he is strong enough to pull through, she will not be able to tell if it is a bug until he goes to the loo.
I have to call back tomorrow and get another update.
