Blood in the stool and diarrhea could be caused by parasites, change in diet, toxin ingestion, infectious viral diseases, blockage in the intestines caused by ingestion of a foreign body, or a mass/growth in the gastrointestinal tract. Please make an appointment to have Smoky seen by a veterinarian as soon as possible, as diarrhea and blood in the stool can lead to dehydration and anemia, and can be very dangerous if left untreated. I recommend taking in a fecal sample from Smoky to your vet as well, as that may aid them in making a diagnosis. Good luck, and I hope he feels better soon!
