In Gaialite, a video game by Fridgecrisis Games, they act as Save Points and sometimes Healing Stations. Thanks, Kitty!
Save Kitty invades the Villages universe to help save the day!
If you have a particularly large village at the end of the round, complete with powerful and useful cards, it might make sense to use Save Kitty's ability. If you have a Builder or a Farmer with neither of them having their counterpart cards, it might be useful to set aside their village, hoping that you gain animals or buildings in the next round. She does cost 2 gold to use, however.
A gamble with saving a high-value Village is that you'll temporarily have the Low Score card even though you don't really deserve it. However, you will be a prime target for attacks by having such value on the field from the beginning of the round.
