My poor Truffle had to go to the vet yesterday as he was squeaking when doing a wee 8... The vet said his bladder felt very hard? He had an anti-inflammatory injection & is now on baytril - poor little boy 
I'm sorry Truffle is feeling a bit rough, Suzanne, will keep my fingers crossed for him!
In no way am I trained hands-on yet, so don't take my word for it just yet (!), but I found that when Jasmine had cystitis her bladder felt a bit "leathery" as opposed to soft. I was assume this means it was inflamed!
