Thanks for all the input on my previous post. I did take Pepper to the vet
and they put her on the Hill's z/d - low allergen.

But....I noticed today that my other cat has diarrhea also. This happened six
months ago (both had it) and that is when the vet put them on panacure (for
parasites). They were okay after (except for a few bouts with diarrhea that
pepper had) up until now. When I originally called the vet to tell her about
the problem, I did suspect that both had diarrhea and she said that it could
still be food allergies/insensitivities and said it probably isn't parasites
since they were already treated and not outdoor cats.

I just think it is too coincidental that they both have diarrhea at the same
time (now and back in Feb and the August before). It's got to be something
they are passing back and forth. Or am I wrong? What do you all think?

At any rate, I have some flagyl that the vet gave me yesterday. I can give it
to Pepper, but there's no way with Maxx. He runs, hides, hisses, bites (and
he is big and very strong - and it's just me here - no one to help); I even
tried to hide it in tuna fish (real tuna fish). Have you ever known a cat not
to eat real tuna? Well, he WILL NOT!!!

Please help. Any idea what's going on? Any idea how to get him to take the
meds?
