Purina Pro Plan Veterinary Supplements FortiFlora Daily Probiotics for Cats for Digestive Gut Health and Diarrhea - 30 ct. Box

Kittens have sensitive stomachs. There's probably nothing wrong with the food you gave her, it's just not what she was used to eating. You can try some probiotics.https://a.co/d/07fCj1lH Or take her to vet. Unfortunately, while the diarrhea will pass in a few days, kittens are small and have no reserves to sustain them when they get sick. Treatment is required.

It's possible that it's a herpes virus, so antibiotics won't help. Probiotics can often help reduce and/or eliminate the tears and gunk. I use Purina Pro Plan Veterinary Supplements FortiFlora Daily Probiotics for Cats https://a.co/d/0duVNF9w. It's worth a try. It helped my kitty.
