lj ate my first reply.

I'm so sorry to hear about the deaths of EmmyLou and her mother and siblings. Did you have the mother and the entire litter? As a fellow animal lover and especially lover of cats, I can imagine how distressed you are. You really have had more than your share of losses.
Such a darling little calico.

I hope Layla stays well and is a ray of sunshine for you. Is there any way she can be treated prophylactically to prevent the disease from taking hold? I hope so.

I wish I could do more than just write a reply. :(
