For the last three days i noticed blood in my kittys stools, his regular vet is off for two days but i took in a stool sample yesterday and they called me, the fecal test came back negative for parasites, i told the them i was most concern because of the blood and the technician or whoever tested the sample said there was no blood or maybe he only checked for parasites, which i know for sure the stool had some blood, anyway, his vet is coming back tomorrow and i can talk to her, whatelse you think is causing the bloody stool, and what type of test you think the vet should do?. He's acting perfectly healthy otherwise and the his poop is very normal, thanks
