Is it safe to give yogurt to a kitten?

i have 5 bengal kitten now is 1mth.one of them had diarrhea. is it save for my kitten if i give to her a small amount of yorgurt

has the kitten been checked by a vet? it could have worms

Absolutely get a vet check first. Worms or other parasites are very common in kittens, and can make them very ill very fast. Take a stool sample in with you for testing...get it as free from the litter as you can.

Once the problem is identified and treated, live yogurt isn't a bad idea. Goat's yogurt would be much better though - the molecular structure is different to cow's yogurt and it's much more readily digested.
