Caspian and Indi belonged to some nice folks who just didn't realize that the Minis had gotten old. Caspian especially had poor teeth and could not eat standard fare any longer.
Their poor health made them more susceptible to lice and infections.
They were just not well in general.
... had them perked up and glowing with renewed health.
They have now been Adopted and are being doted on appropriately. LOL They are MUCH loved!
Caspian passed away from shear old age. He was much loved, right to the end.
