A good Compounding Pharmacy that deals with Vet meds should be able to make up the pill you have, it's a really good tasting flavored liquid...... there's usually several flavors to choose from; beef, chicken, tuna, etc.
Try doing a search on Google for these words: compounding pharmacy vet meds _________ (in the "blank", enter your state or city). you may not find one local to you but many will compound it up and ship to you....all they require is for your Vet to fax them the prescription for the medication......or, on the case of a med that's non-prescription (say a supplement or amino acid), they would just do it according to your direction.
Here's one that's well known:http://www.smithspharmacy.com/retail...8D577B01E035A1
They can often also make up the medication into a handy "gel" that you massage into the cat's ear!! -- which not only makes it easy to give but no side effects to the tummy
EDIT:...............sorry, the site above is in Canada (though I'm sure they compound for Americans)....not sure where you live. Here's one in the U.S. and it also gives a list on this page, of the various meds they can compound and what "form" they can compound them into (I'm sure the list isn't exhaustive; it would pay to contact them if one you're giving isn't on the list)............I see the Baytril (Enrofloxacin) can be made into a transdermal gel..........that's awesome, wish I'd known that years ago but glad to know it now!!!http://www.pethealthpharmacy.com/medications.htm
