R.I.P little Ninja

Around 9pm tonight my baby Ninja left this earth....it hurts so much. We came home and he was lying there trying to breathe and I could still hear his heart beat, but we don't know what happened to him. We rushed him to the Vet and the Vet brought him out and told us he was gone. We tried to give him CPR, but it just didn't help. We are going to miss him dearly may you rest in peace my little one.
