I've moved several times and it is easy on the critters. I block off one room in the new place and put blankets with our smell for them to burrow in along with litter and water. They won't be interested in eating. The last time I moved the cats before I moved the stuff.

I have no advice for a semi-feral. Is he an indoor-outdoor cat? Your vet is the best bet.

Mine followed me everywhere for a few days after the move. They wouldn't explore unless I was with them. I only had two at the time. I can't imagine moving now that I have five, plus one foster.

Good luck!
