Blocked Bladder: Case History #2

I have a male Persian, now six years old, who began to have repeated urinary tract blockages starting at about three years old. He would be hospitalized and come home and be fine for a few weeks, sometimes a couple of months. Then it would happen again. A few times it was touch and go whether he would make it. He had been on all the special medical dry diets and was drinking only distilled water but nothing seemed to help. I tried a raw diet and some of the canned special medical foods for cats with urinary problems but he wouldn’t touch them. It got to the point where he was blocking so often I was sure one day soon I would lose him altogether.

A Suggestion

A breeder friend suggested I try giving him DL-Methione (an amino acid) to help dissolve the crystals and acidify the urine.

Another breeder suggested he be given a course of Baytril for a few weeks to see if that would help. I have a wonderful vet who was agreeable to trying a new approach and gave me what I needed to treat him.

The Soup

I started the Baytril and began to feed him what I call a/d soup—just lots of distilled water mixed in with the Hill’s a/d (which he loves) so that he was getting lots and lots of water. I watched his urine output closely and at the first sign of any straining I gave him one tablet of Ketoprofen for pain and to help him urinate. Then I dissolved a DL-Methione tablet in water and syringed it into him. The pain medication allowed him to urinate while giving time for the DL-Methione and increased water to begin dissolving the crystals. Again, it is judgment call about the severity of the blockage and if the vet should see him. If a cat is completely blocked, you need to have him examined by your veterinarian quickly.


It has been 1 ½ years since I started him on his new diet and he has not had a blockage since I began his new “protocol”.

Fine Tuning

  • He receives a ½ can a/d morning and night sometimes with water added and sometimes not.
  • He has Science Diet ID dry food down but seldom touches it. It often seem to upset his tummy when he does eat it.
  • About two or three times a week I add some water to the AD to make it soupy to increase his fluid intake – just as a precaution.
  • I also watch his water intake and give him fresh every day to encourage him to drink as much water as possible.
  • I haven’t had to use the DL-Methione for many months and he receives no medication at all.


While a/d is not recommended as a full-time diet for cats, in this case, I felt the benefits greatly outweighed the drawbacks. I would rather my cat be alive and healthy then gamble I might lose him by putting him back on a medicated dry food diet again.

I plan to try him on another brand of high quality dry food in the future but will do so cautiously and not take him off the AD completely. He has good weight, good skin condition, is loving and affectionate and would not be happy if I took away completely the a/d he loves so much. Whether this approach would help another cat I cannot say. It did correct the issues my male was having, so it may be worth considering if more conventional treatments fail.

NOTE: This protocol to manage my cats blocking issues was followed under the complete supervision of my veterinarian. Please, if you have a cat with a blocking problem, and want to try this diet for management of the condition, discuss it fully with your veterinarian first.

Persians took London by storm when the breed was showcased in the world’s first organized cat show in 1871 at the Crystal Palace. The day-long exhibition also featured Siamese cats, a Scottish Wild Cat, and Manxes, among other exotic felines. Proving that cats were popular long before the Internet, the event drew more than 20,000 visitors. It also shouldn’t surprise anyone that a Persian kitten won “Best in Show.”
