These are all symptoms of the Calici virus.... part of what is in the Feline IV shots. FVRCCP .... Feline Viral Rhinotracheitis, Calici, Chlamydia, and Panleukopaenia. Some vets only give a 3-way shot, which does not have the Chlaymydia. Unfortunately many kittens get these diseases before they are of age to be vaccinated .... because their moms have never been vaccinated, but the mortality is much higher in babies!

Good luck, QSA ... prayers for the babies and you!
