My kitten has watery eyes and diarreah. She still has a tremendous energy level - but for the last three days has had diarreah. And since yesterday her eyes are watering. I saw on a post that the diarreah is not a big deal - but the person answering asked if she had watery eyes too. Should I be worried?

I read that when a pet has diarrhea give them some pumpkin and the fiber helps stop it.
You maybe should check with the vet to make sure it isn't anything serious. She may just have a stomach virus or a cold.

Actually diarrhea IS a big deal. It can rapidly cause dehydration especially in a young animal. DO NOT use pumpkin--at this point you do not know what is causing the diarrhea and stopping it may actually harm the kitten.
Do bring her to the vet. Depending on her age, it is most likely and upper respiratory infection and intestinal parasites--both of which are very treatable.
Good luck.
