kitten with blood in stool
GrizleeB posted:
My 12 w/o kitten is showing blood in his stool today. I found him abandoned two weeks ago. He's been to the vet and stool sample was fine then. He's had his first shot and was given deworming medicine. I'm concerned for him, but I'm also concerned for my 13 y/o cat. Is worry in order? I know the kitten has been eating voraciously- even the dog food, which I've been trying to keep from him.

Hi there,

If you are seeing blood (as in red blood) that may be coming from the lower bowel or colon rather than the upper bowel and stomach. Is there any diarrhea?
Sounds like your veterinarian is getting him on the path to good health with vaccinations, deworming and a stool sample. The sample should have picked up any parasites, but is not 100%. the deworming should cover most infectious problems.
The key to more diagnostics, there is a pesky little parasite called tritrichomonas that can cause kitten diarrhea and blood, but the key is diarrhea. If there is none, I would consider limiting your kitten to good quality kitten food and monitoring it. Continuation of the blood is not a bad sign but I would speak with your veterinarian again for their recommendations.
Speak also to your veterinarian regarding your older cat. I just rrecently adopted a new cat to hang out with my older cat. Besides making sure she was healthy, I had her checked for the less common viral diseases these days FeLV and FIV. They do not directly cause bloody diarrhea.
Again, your kitten may be fine perhaps with a limitation in diets but it might be nice to check in again with your veterinarian.
Dr. Sandy
