I can understand how you feel.
Cats can't cope well with not eating- they really need their food. Even with kidney kitties like Filou it's better they eat too much protein than too little and we always watch him carefully as he is not supposed to lose weight.

I am so sorry for you and Nakita. It would be time for a miracle and we'll keep fingers crossed for that.

Love and hugs to you and the emerald girl.
