of course I didn't move them into empty houses, I added them to various families in the game and went into the households and provided them with food bowls, beds, litter boxes, toys and everything. The ones that were adopted are now fine, my problem is that the games keeps generating more. Not as much as in the beginning, but still. Apparently I'm the chosen one, because from what I've seen other people have encountered very few strays. To me, there are lots of them. I have tried initiating a new game, but then it was back to five or six strays showing up near my home everyday.
