I am so sorry to hear that Shemp has crossed to the rainbow bridge, but I'm sure he's there somwhere amongst a pile of cats having a cuddle and having a nice rest with all the others, his friends that he can meet again and talk about their dad and the good old days, and speak of the day when he will meet you again.
My most hearfelt wishes to you Gary, you are a super pawpa to all your cats and Shemp loved you dearly. Shemp is one of the first siamese/tonkinese cats that I encountered on Pet Talk and I'll never forget him. He also introduced me to the phrase 'meezer' which I'd never heard before!
You will be missed by all Shemp, Rest In Peace
Love Kate, Jack & Sunny
