Poor Pouncer!!!
(my thoughts might be a little disorganised but........)

-Rutherford never had problems since his PU surgery (he is the only cat I ever had that done)

-Crystals can (obviously) still form after the surgery, but the food is suppose to prevent that!

-Biddy's crystals were NOT going away even with the c/d, so the vet put him on Ammonil, a urine acidifier, pill. Pouncer might need something like that.

-I realize that this is a mute point now (since crystals were found) but cats can block from things other than crystals (as Jim did).

-Is Pouncer eating CANNED urinary food? It is suppose to help more than the dry alone. (Jim won't eat it though, so )


Anyway, at least by the time I saw this Pouncer is diagnosed and on the way to health again.
