Hi guys. Sorry if I am posting too much but I love to hear what you all have
to say.  It has been a month since Trouble's blockage and on Friday he went
in for a full physical.  His x-ray showed an absolutely perfect bladder with
no stones and when they passed the catheter for a urinalysis, there was no
resistance whatsoever, no inflammation or infection.  The vet said that if he
did not know that this cat was ever blocked he would say that he was perfect.
At the time, he actually said he was beginning to wonder if Trouble was ever
blocked at all.  I spoke with the vet again today and he told me that the
urinalysis came back and showed that Trouble's ph level is 7.  Not good, but
not bad.  He said that we have to get that number down.  There are still some
crystals in the urine, but no blood or proteins were present.  Thing is,
Trouble will not eat any of the food that is recommended to bring the ph
level down.  I just tried the 4th brand with no luck (I have tried Hills s/d,
Hills c/d, Purina UR and Friskies Special Diet).  He is eating the cd dry
with no problem, but that is obviously not cutting it.  

My questions are, is the ph level of 7 dangerous?  Is he more at risk for
another blockage?  Do "normal" cats have some crystals in their urine?  Any
suggestions for bringing down his ph level other than using food?  

Thanks in advance everyone and I look forward to hearing from you!
