For 2 months I have been taking care of my parent's cat, Foggy, a very frail (20+ years old) calico. Well, for the past few days I have not seen her anywhere - not in the house - not outside. Last time I saw her she looked really tired and very "old." My fear is she has wandered off to put herself to rest. I have searched the entire house in hope of finding her sleeping in some remote corner, but no luck. I talked to a few cat people and both have assured me that cats do have a sense when their time is near and tend to find a safe, quiet spot to go...though I am still keeping an eye out just in case. Anyway, we miss her and glad she had a great life.
