<human>: I've had this kitten for about 2 months now. When I first brought him home, he had very runny diarrhea with bright red blood in it. I took him to the vet right away, and he was dewormed. 

After this, he was fine for a few weeks (minus an eye infection that was treated, and got better). His poop was solid and he had no problems with the litter box.

Now however, he's had diarrhea for the past 2 weeks. Not as liquid as when I first got him but definitely not as solid as it should be. Last week I took him in and the vet gave me some medication for it. He seemed to get better for a few days, but today I noticed some more blood (a very small amount) in his semi diarrhea poop again. (Also, he is now out of his medication)

I dropped off a stool sample at the vet, and I should have some results by tomorrow. I'm just worried about him, and I'm concerned that it could be something more serious.

Is it possible that the first dewormer didn't kill the right kind of worms, and he still has a parasite? Does anyone have experience with this, and if so, what was the cause in your situation?

Can you provide a brief overview of the text?
<bot>: My kitten has bloody diarrhea and has already been dewormed. Waiting on some results from the vet. Any ideas on what it could be?
