answer:I am so sorry to hear about this, it is very difficult to go through. I have adopted a number of older (some sickly) animals and have had to make this decision fairly often. It is never an easy one and very often these days vets will not recommend euthanizing for fear of later legal action. Think of this as a gift you can give your dear friend, a quiet end to suffering, with dignity. Be there with him, stroke him gently and talk to him sweetly during the process. I would like to have that option myself, when it’s my time. As to when, you will likely second guess yourself for awhile, but consider the timing. When the not-good number of hours in a day are more than the good ones, I take that as an indicator. Don’t beat yourself up about this, it is a positive thing that you are in a position, after caring for him for years, to do this for him. Good luck with this decision, @deni , I wish you and Barnabas peace with the decsion you make, however you make it.
