Why is my kitten's poop still bloody after parasite treatment?

Updated on September 23rd, 2025

Pet's info: Cat | Mixed Breed | Male | neutered | 3 months and 28 days old | 9.5 lbs

I got Chatran at the Humane Society 5 wks ago. He was treated for parasites there when younger. His recent fecal test was positive for a parasite and he was prescribed Albon, (finished dose 3 days ago). There’s been an occasional drop of blood in his poop before, but today there was more. His appetite hasn’t changed and he’s playful as usual, except yesterday he was a tiny bit less playful. He doesn’t seem to be in pain. What could this blood be for?

Hello, sorry to hear about Chatran. Often frank blood arises from the colon or large intestine, as bleeding from the small intestine more commonly results in dark, tarry stools (melena). Its likely that the small amount of blood you are noting is coming from persistent colon irritation which can be seen with parasitic infections. It would be ideal to have his stool re-tested for parasties to ensure the albon has treated this infection completely. Some pets, despite being treated may continue to be infected or have re-infections that require longer treatments. Have your veterinarian test another fecal sample. Hope this helps and best of luck.
