Have you phoned the vet? I would call and tell them you're stopping the clindamycin. Don't give your cat another dose. Since I don't know what the antibiotics were originally prescribed for, it's possible your cat may need another type, but definitely stop the clindamycin. To help deal with the diarrhea right now, get some high-potency probiotics in capsules from a health food store and sprinkle a bit in some wet food for a few days. Slippery elm powder (also from health food store) might be helpful as well.
