Hi there. I'm really new here, but not new to the world of pets and worry. About Martha, you're doing the right thing in putting her to sleep when the time is right. I've been through this three times with my dear kitties. It's so merciful. You'll know when the time is right. Don't wait until the point of suffering - that's the whole reason behind euthanasia - no suffering. The mind set to get into is that you must do what's easiest for her even though it's incredibly hard for you. And when the time is right, don't let her know you're struggling. Speak gently and sweetly to her and keep her as relaxed and calm as possible. The goal is to make her passing gentle. Have the vet dim the lights and take her to a room where dogs aren't barking, etc. I'm sorry for the position you're in - you must be beside yourself. :aww I was thinking on the baby Sunny that her blood sugar may have dropped, making her lethargic and uninterested in eating. Sometimes a little sugar water gives them a little energy jolt and awakens the appetite. This scenario happens a lot in tiny puppies and kittens. I know that's a simplistic solution, but it could really help. You probably have to carefully use an eyedropper since she doesn't feel like doing it herself. I believe it's best to slowly drizzle the liquid along the edge of the beak as opposed to opening the beak, to avoid aspiration. My thoughts are really with you today!
