Sat wolfs remain sat - you can't unsit them once you have sat them and return to the game the following day.
We also have just friended a pack of 4 wolves then dug in while we had our dinner and came out of the game. When we returned to the game all the wolves had unfortunately disappeared.
All the best,
The WoolyWiccan
