Called later in the eve and the blockage is passed and he is doing well. They say he is hissing at them any time they get close so that is music to our ears. Little forker is a pain for sure.
UPDATE: Picked him up this morning and took him to our vet. Seems he was not the most cooperative. He still has the catheter in and we hope to be able to get him home this afternoon or evening. He was pretty fidgety in his carrier in the car. Betting he just wants to go home and sleep.
