Carol, my cat Bobbie( Roberta ) is also 17 years old, until this week she was always outside but with it being cold she found her way into my sewing room and is now sleeping on a new carpet square under the spare chair, out of my way and feet. She does not want to move so I had to take her out to the water thinking she will get dehydrated if she didn't drink. I don't think she has eaten anything either. I will try her out later to see if she is alright and just cold.
