I am soooooooo sorry for you and Toby. Please dont feel guilty about any decision you choose. I know you love him very much.
About the rigidity, could it be a posturing thing from lack of oxygen when they were trying to revive him? If you can talk to your Vet that began the procedure I would ask how long did he not have a heart (or do you already know this?) Is the 3000.00 to run test, IV's and watch him? Or what exactly are they doing for him? Maybe it could be a liver shunt like others mentioned. It is really hard to give advice not knowing all the details but do know ..I am sorry you are going through this. I will continue to pray for Toby.
