Dr. Andy :

No diet change!

Dr. Andy :

First, you need a urine test to confirm the current urine pH and what type of crystals are present.

Dr. Andy :

Once you know that, your vet will know how to swing the diet to impact the urine pH correctly.

Dr. Andy :

Second, a urine culture needs to be done to identify what bacteria is present during these episodes. 2 reasons why?

Dr. Andy :

1. To confirm there is even an infection? Even if responding to the antibiotic, it may not be the antibiotic that is helping. Cats can get idiopathic cystitis or feline urinary tract disease. It can appear as straining to urinate with blood and no infection. So, it can resolve on its own, sometimes, so maybe its clearing as a result of time and not the antibiotic.

Dr. Andy :

Plus, if there is an infection, the culture and sensitivity test would tell you exactly what is there and the best antibiotic to kill it.

Dr. Andy :

Also, with repeat infection!!!!! make sure your vet is giving you at least 3 weeks of antibiotic, not just 7 to 10 days. Very important

Dr. Andy :

No diet change at this point.

Dr. Andy :

I can't get her to drink enough liquids....tried milk, broth and clam juice. One of the other vets suggested science diet. I took her off of the uretic 2 mo. ago cause of a possible food allergy...her nose is always red and she itches it. A month after I switched from uretic to anergen she started this squatting. Then 1 week ago I switched to the science canned diet for
urinary I am confused about her food. Checking the ph sounds good but her last urine test showed no infection just blood in it. So........that's were we are at. I recently had a panel of blood work done (2-3 Mo ago) just to check her out...and she was really great..........

You need to move away from these less familiar foods for managing a problem like this...

It's not only about the urine pH. A urinalysis tells a great deal of info:


We need to know if there are white blood cells present, crystals, etc...

I am actually suspicious that diet may not help at all if your cat is having the idiopathic cystitis condition.
That can be caused by stress!

The fact that the last urine test showed no fection does support cystitis!

So, your cat would most benefit from pain medication like buprenex (given orally), supplementation for stress:

Feliway Spray

Pheromone Collar NurtureCalm

Potential treatment options for Idiopathic Cystitis or Feline Lower Urinary Tract Disease include:
1. Phenoxybenzamine
*Helps to relax the urethra to make urinating easier
2. Cosequin for Cats
*May help to protect the inside of the bladder wall
3. Buprenorphine (Buprenex)
*Incredible injectable pain medication that can be given orally to cats in very small amounts.
4. Royal Canin Urinary SO diet or other prescription diet designed to reduce certain
Minerals, change the urine pH, etc…
5. Increased water intake can be beneficial either by using a canned diet or
stimulating the interest in drinking by purchasing a running water kitty fountain.
6. Whenever a urinary tract infection is suspected, the veterinarian should also
Perform a “culture and sensitivity” on the urine at the laboratory to confirm an infection, identify it, and know which antibiotics are best to kill it.

That's about the most I can help.
