Donna you got me crying too. I went through a similar thing with Taz.

I agree with Donna and Gary. It sounds like Irwin is doing well right now since the stones are gone. I would try the medication and food and see how that goes for him.

I remember when Taz was very sick and all my PT family kept telling me "you'll know when it's time". I didn't want to face that fact AT ALL. But the last time he went to the vet she said "I would not try to stop you if you want to let him go today". Well of course I didn't WANT to. But she said there was basically nothing left to do for him. I'd done the fluids for a few weeks with no results. It was time even though I didn't want it to be. I also stayed with him while he went. Oh man, all those emotions are rushing back to me right now.

Irwin is sooo young, I hope he has a few (if not more) years left with you. And you should know when he's had enough.

Good luck! And I'll keep Irwin in my thoughts.
