My cat had PU surgery almost 2yrs ago.  It cost about 1,000.00 dollars.
However, it was very well worth it.  I praise the vets that performed
the surgery. It is not one that is done often here, so he had to call
in an additional vet for assistance.  This did fix his immediate
problem which was a blockage in the urethra. I currently treat the
struvite crystals by diet.  I feed my cats (all three have to eat the
food now) purina ur.  I was told that if this did not work, I would
have to use an oral medication to treat the crystals. I'm wondering if
anyone has tried any other cat foods for this specific problems with
much success? My cats like it ok, they definitly do not love it. They
do make a canned version I give them mixed with water (keeps them
hydrated and makes sure the culprit ingests enough water to help dilute
the urine and crystals) only as a treat.  Occasionaly we run out and I
panic as to which foods to get from the grocery on a Sat or Sun, due to
the vets office being closed. Any suggestions would be greatly
appreciated.
Thanks a lot!
