I have a cat that is only two years old and is being treated for tapeworm and coccidya. There are also two othere cats in the same house all three had bloody stool and that is what prompted the stool test, Since having the medication two of the three cats have shown significant improvement but one is very uncomfortable. He crys a lot he eats often but not a lot, he just is not himself. Should I be worried or should I just wait and see what the results of follow up stool test will be.

Thank you for any information.
Marsha
