They are on wet food from the vet and are confined to the porch right now... I don't know how to keep them from being in the space where they are sick if they are in a confined safe space...
They were in the kitchen for the first day or so that they were here and then were fine and roamed the house. They only got sick last week (after being here for 2 weeks fine).
They are a LOT better today than they have been so hopefully the meds from the vet are doing the job....
