My Samantha has to be part siamese even though she is black. She has the siamese sound and is more verbal that the rest of them all the time but Giz has been extreemly verbal since the weather warmed up and I had been puzzeled about it until I remembered how much more verbal Samantha has been. Even Amy is talking more than she ever has.. I think it is the weather with mine and how glad they are that the windows are open.
