Dakotah, our domestic shorthair silver tabby classic and white show cat, is sitting on my lap as I type this. He sleeps about 20 hours a day so I'm honored with his presence. I don't envy you in the least. I have been through it before. The only thing I ask is that you do what's best for your companion and not yourself. We tend to hang on to our compatriots too long because we can't let go. I don't want to see him/her suffer because of that. Only a vet can answer that question. Reaching out to others can help. JLC
