My heart goes out to you. My foster kitten had FIP but I idn't know it until I adopted him out to my friend. She took him to the vet for a reoccuring resp infection (he was on meds with me, finished them and was fine but the stress of rehoming brought on another) and the vet told her he had FIP. He died not too long after that. It was a terrible way to go.. you did the best by having the kitten PTS before things for real bad. *HUGE HUGS*
