My cats had cow pies 1-2 x a day for a few days, then would be okay for a few days then back. Every cat handles this differently. Some have non stop diarrhea, some soft - cow pie intermittently. It goes back and forth. The reason antibiotics seem to help is because they kill the good bacteria as well as the bad, leaving nothing for the TF to live on. Once the meds are stopped it returns. Stress and food changes are the major triggers. Suspecting food is a common mistake Vets make. I don't know what pathogens Albon is effective against but if your cat has Clostridium and Albon is not effective against that she is going to continue to have diarrhea. Also Clostridium HATE fiber and Thrive on carbohydrates, that is where food comes into play. They do very poorly with protien diets. My cats are so sensitive to change that 1/4 tsp. of something new can cause diarrhea. I now have a regimen going so we only get diarrhea every couple of weeks, they still have TF. Cow pies still occur in between at times but I am able to manage it with what I give them. Remember, your kitty is young, mine are almost 3 so they have been dealing with it all thier lives. I went through tests, diagnosis of IBD, food allergy, parasites, clostridium, you name it. Many Vets consider this a fairly uncommon disease, but it is not. At an International cat show 33% of the cats tested had this, that was some time ago. Shelters are having a time with this too, it is no longer uncommon. I don't know why your Vet is reluctant to test, maybe you could ask her to call Dr. Gookin, that is what mine finally did, she is very helpful. As with Tamgirl I too am the one who educated my Vet and continue to do so. She had only heard of it, and all she now knows comes from what I have researched and brought to her.
