"Missing" cat

When I arrived home from attending the afternoon mass earlier this evening, I noted that our sick black cat was nowhere to be seen. (Our other cat was on top of the cage in the laundry as usual.) She was not waiting in the driveway as usual nor was she in the back yard. I began to get worried and looked all over for her but had to give up after a futile search. Only when my parents got home much later after attending Holy Hour at our church did I learn that my father had brought our cat this afternoon to the vet's for a check up and that the vet had advised that she be confined at the clinic overnight for observation. What a relief! I had thought she had gone to hide herself in some obscure corner as many sick animals tend to do.
