Thank you for replying. I appreciate it.

I actually have a "Tucker," too!  But my cat, Omar, has IBD and is also on
metronidazole -- my vet orders it from a California compounding pharmacy
(Triad) and it is a fish-flavored liquid.  I have 2 other cats on a liquid
medicine (clomipramine); another vet at the same office called this
prescription in directly to Pet Health Pharmacy in Arizona for compounding.
They have been a really prompt and helpful pharmacy and I might consider
changing over to them for the metranidazole.  They can also flavor meds with
all kinds of flavors -- currently, my two are getting the Triple Fish
flavored clomipramine and seem to do okay with that taste.  The liquids seem
to work better with my cats especially when medicine dosages need adjusting.
I ask for a syringe because I think the droppers are harder to use.  Maybe
this will give you another option to try.

Also, if your kitty has digestive problems (maybe allergies like was
mentioned -- maybe, he has IBD, too?) you might find you have better luck
with using canned food -- I have found that Omar does so much better with
canned food like Wellness and there is another brand I use, too, called
Precise -- I do buy these at a local pet store because the large chains here
(Petsmart; Petco) don't carry them.  The greater moisture content in the wet
food helps him and also these foods have much fewer grains than most
commercial dry foods.  My kitties only get dry food (and I use, California
Natural, Chicken and Rice, also from the local store) as a "treat" for
taking their medicines so they are more inclined to be cooperative.
hope this helps,
Christine B.

Thank you for replying. I wouldn't say the runs, it's just 10-15 times a
day. I have taken a couple of samples into the vet and the doctor looked
him over, but no actual tests on him.
