It's so tough, even reading your post, just tugs at the heartstrings. It's so sad to think that money has to enter into our decisions where our dear furkids are concerned but this is the real world and nothing is free; nothing of value anyhow, except for one thing: the air we breathe. And Tiger just isn't getting his fair share of it. Whatever decision that you, your husband and vet come to, it will be the right decision. I know that money isn't the only factor, to be sure, and that the primary concern is that you want what's best for Tiger and his longevity and also his comfort and quality of life. We'll keep the prayers going for your sweet boy and for you, your husband and your vet. We'll do our best to prop you up and support you in any way that we can. More (((HUGS))) and hand holds coming your way....
