diarrhea in cat, won't eat food from vet

Wed night Jingles butt exploded. It was loud and could be heard from rooms away. She had diarrhea. Thurs morning it was the same thing so I took her in the vet Thurs night (another diarrhea poop during Thurs during the day too). They took her temp (normal) and gave her fluid under the skin to make sure she wasn't dehydrated. He gave me some cans of Science Diet ID and said it's a bland diet which is what she needs. After the diarrhea was gone I was supposed to reintroduce her to her blue mountain dry food slowly. Oh, and he gave me probiotic pills to sprinkle over her food twice a day for 10 days. I also have to take a stool sample in to be checked for parasites.

I gave Jingles the can food Thurs night and she wouldn't touch it. It sat there till Fri morning w/ out one nibble. She was begging for food so I gave her the usual dry food. She ate it.

Here it is Sunday morning and she still has diarrhea loose poops. They don't explode out of her butt anymore, but it's still diarrhea. I've been giving her the regular dry food cause she won't eat the can food from the vet. I did try mixing some dry w/ the can stuff. One bite. No more. She does eat her dry w/ the probiotic sprinkled on, so that's not holding her back.

Any suggestions?

Jingles is about 1yr old. She was adopted in late Dec 2010 from a shelter. She's had all her checkups w/ the vet since we adopted her and is fixed. Wanted to add that just in case it's helpful.

Try boiling some chicken (plain water, no seasoning) and then let it cool. Shred it and mix in some of the broth until it's the consistency of chicken salad or oatmeal. You can also cook some plain rice, again, no seasonings or butter. Add a bit of the rice to the chicken mixture and see if she'll eat that.

Did the vet give you Metronizodale? That's usually what's prescribed for stopping diarrhea.

I would also ask about the metronidazole in case your cat has giardia and an intestinal infection. Has your cat been wormed? I am sure the vet already asked about this anyway. But Jingles should be wormed twice at three weeks apart. The I/D is a good diet for clearing up the diarhea along with the probiotic. My cats seem to love the I/D when I had to give it to them so I was lucky. There is a couple of other prescription diets other than Hill's. Eucanuba and Royal Canin make some too. If you get the script from your vet, you can go directly to Petsmart and buy the canned foods there. Good luck with JIngles and hope she feels better soon.
