We have been feeding some strays and semi-ferals on our back deck and fixed some boxes for them which they sleep in at night. For the last two months we have been feeding them wet food several times per day due to the severe cold where we live (near the Great Lakes). They really like the wet food and have been feeding them that several times a day to get them through the winter. Will they go back to eating the dry food when the temperature gets a little warmer, the wet food is getting to be expensive since we go through a couple of cases per week when it gets real cold. Also, at what temperatures will they not need boxes to sleep in. Thanks for suggestions.
