Hi, my 8-9 week old kitten went through deworming with 2 doses and 2 weeks after the first dose he began having diarrhea once a day, now about a week after the second dose his anus sometimes is red and so far he has not had a poop today, the red looks like inside his anus and it's only about the size of a pen tip, I only seen it once today and he doesn't seem to be in any pain and he is acting normal and playful, I have a 2nd kitten that was dewormed and he is not experiencing anything

Hi there and thanks for using Petco Pet Education Center, formerly Petcoach. There are many causes to diarrhea with a red perhaps inflamed anus. Parasites could be the cause or a bacterial or viral infection. I would take your kitten to your veterinarian soon for a fecal test where they will test his stool for parasites and bacteria and/or certain viruses that could be causing the diarrhea. They may Rx a medication to your kitten depending on what the veterinarian discovers on the fecal test. Best of luck! I hope this has helped.
