I have a question regarding my cat with FLUTD. My cat had two
episodes of being blocked so the doctor recommended him eating a
prescription food, Hill's c/d-s. The cat would not eat it at all,
neither canned nor dry, so instead the doctor recommended that we put
Uroeze (Ammonium Chloride) in his normal wet food. This worked well
and the cat ate the food. Sometimes as a snack, my wife tried giving
him the dry Hill's c/d-s food and he began to eat that. Recently when
we spoke to the doctor he told us that the cat should not eat both
food, only one or the other.

This does not make much sense to me. The analogy that I used was if a
person was vitamin C deficient and a doctor said, "You can eat 10
oranges or 8 lemons a day", it would be perfectly legitimate to eat 5
oranges and 4 lemons and you should still get the same amount of
vitamin C. Or another analogy would be if you were trying to eat low
fat foods, you should be able to eat any low fat food, not just one.
The same logic should apply to the cat foods.

Mark,
Your veterinarian is quite correct on this one. If you dose the cat
with Uroeze according to directions and then add in a food which is
designed to acidify the diet to the proper range of 6.2-6.4 you run
the risk of over acidifying the diet and endangering the cat with the
formation of Calcium Oxalte crystals which form in aicd urine below
6.2.
