On 11/04/07 our 13 year old female cat (Orchid) died of cancer. Her surving "sibiling," a 17 year old female Siamese (Matilda) with chronic renal failure, has never been without a feline companion, and now finds herself alone. She has taken to yowling in the night. She has a heated cat bed, into which I have placed a large stuffed bear, plus her bed is near the woodstove. At one time we had four cats, and she is the only survivor. We have never encouraged the cats to sleep with us. Since Orchid died I've taken Matilda into bed with me a few times, but she always leaves. Does anybody have any ideas? I'm hopeful that time and lots of love will take care of this. So far she is eating and drinking well, and looks good. Thanks.
