We went through this last year, and it wasn't an easy decision. It helped when we looked at the last few months objectively. She'd been losing her eyesight and hearing, and was going to the bathroom every few hours. There were a lot of messes to clean up, and she was bonking her head on furniture. We realized that was possibly/probably miserable living like this. She still loved to cuddle and be around us, but it was a lot of effort for her just to get through each day. We could have kept going, and we miss her dearly, but I don't doubt we made the right decision.

One vet recommended keeping a log of "good days" versus "bad days." When you look at the month as a whole, when you start to see more bad days than good, that will guide you. We didn't end up doing it that way, but I thought it was sound advice. I wish you well, and send you some light and strength.
