It was a difficult decision for my wife to make either way, but Zoe came home from the vet on Thursday. She was at least eating a few days ago, but over the past couple of days, that too has stopped. Her back legs are getting gimpy. At night, she cries every couple hours like a baby, begging for water from the sink. Because of her legs, even that is harder. At least Zoe still purrs when you pet her or she sits on my wife. Since it is unlikely Zoe is going to magically get better, my wife is planning to bring Zoe into the vet tomorrow and have her put down. All we can do until then is make her comfortable.
