Great! Definately a small price to pay for peace of mind..........

No! That is absolutely *not* a reliable method for determining if a cat has
a urinary tract obstruction -- *especially* in a potentially fatal
situation -- . For instance -- if an obstruction occurs in a ureter - or in
the renal pelvis, urine flow will be occluded *before* reaching the
bladder. urea diffuses back across the renal tubules and increases the BUN.

Another erroneous ASSumption.... Urethral *plugs* -- not crystals or
uroliths are the most common cause of urinary tract obstructions in male
cats. Feline urethral plugs are made up of a lotta organic matrix (sloughed
tissue, mucous, cells) and small amounts of crystalline particles. Uroliths
are composed of just the opposite - more polycrystalline concretions and
very little matrix. A urethral plug is analogous to fruit Jell-O: the
matrix = the Jell-O; the crystalline particles = the fruit pieces suspended
in the Jell-O gelatin.
What made your vet ASSume the problem was caused by crystals rather than the
more commonly diagnosed urethral plug?
> gave me Amox/Clavamox and IVD unrinary care food
Prescription diets have little, if any, affect on organic matrix. Also, how
did your vet know which urinary diet to prescribe without an analysis?
Feeding a diet formulated to dissolve struvite to a cat that has a tendency
to form calcium oxalate will *promote* the formation of calcium oxalate --
Calcium oxalate *cannot* be dissolved in cats and usually requires surgical
removal. OTOH, a diet formulated to inhibit the formation of calcium
oxalate will *promote* stuvite formation. Fortunately, struvite can be
dissolved - but not without significant risk.
If your cat didn't have a crystal problem before, he may be in the process
of developing one... thanks to your vet's unique intuition.... Did your vet
have the common sense to at least check your cat's urine pH?? I'd seek a
second opinion if I were you, and order a complete analysis....
> Cost $222, but it's worth it for peace of mind.
Wow! I wonder how much your vet charges for *good* advice!..... Probably
double....
Your cat needs a different vet... quick, if not sooner.
Best of luck..

The fact that he can pass urine.

Kindly explain how and why you/your vet believes a partial obstruction
caused by a crystal/urolith would be any different in relation to urine flow
than a partial obstruction caused by a urethral plug.
