Good to hear about Storm. I am sorry to hear that Pearl is aggressive towards Sunny I must admit- this is how I could have learned earlier that something was wrong with Tigris. Tigris had always been bullying Filou (not all the time, but once in a while) and some weeks before we noticed Tigris was sick I was surprised to see that Filou chased him and pounced on him.
These kitties have not invented the idea of pity- they rather do not want a sick member of the gang around
But it's good to hear that Sunny eats.
