Cathie I am so sorry for your losses. I was not aware you had also lost Einstein, and now Curly Sue.
Earlier in the week you may have seen that Zinger passed away also from a seizure of some kind.
I have Zing's littermate, Bones. Bones is very food motivated and has NEVER missed a meal. Ever.
He refused his breakfast that morning and I could not for the life of me imagine why. Now, I know why. I swear they do know somehow.
Rest well sweet Curly Sue and Einstein. You are loved.
