I know you all must be getting very tired of hearing this but when I was cleaning out the litterboxes this evening, I found more very mushy poops as flat as pancakes. I know that they're from Starr. Since I wasn't the one to pick the meds for him, I wasn't even sure what the panacur liquid was for so I looked it up on the internet. It's a dewormer. I bet that this is what's causing this. At least I hope this is all it is. I also looked up more info about the fortiflora and it sounds like a very good product for a cat like Starr. I'm not giving up just yet but I hope that he'll continue to poop in the boxes.
