Great to hear that she is eating hay, that's always good to see. Is she pooping okay?
Sorry to hear of the anniversary of losing your precious Buttercup. It's always a hard time anyway so for another piggy to be ill at that time is always worse as you just can't help thinking of your previous loss.
I lost my Bear just over 3 weeks ago and I lost him two days short of when I lost my previous gorgeous piggy, Rory. As Bear had been ill for two weeks, it felt like October was a horrible month, but I'd actually adopted Bear in October, and now after losing Bear, I have just adopted two boys.
It's easy to think of the bad stuff that happens and sometimes we need to remind ourselves of the good that happens too.... like Kona coming into your life.
Whatever happens, please be kind to yourself and know that you are doing all you can to give Kona the best care possible.
Sending you big hugs
