OMG.... I'm really sorry about Arthur.....I don't know what happened other than he is at the RB with so many of our beloved fur kids. My deepest heartfelt sympathy to you and your family. I pray that he finds my Rotti, Nikita and all the other babies from PT and has the time of his life meeting new friends.
(((((((Healing hugs to you)))))
Rest in peace dear Arthur with all the angels. Soon you will have dear Cappy with you.
