I am trying the LTW of adopting strays for the first time and I came across something kind of interesting. I too have rarely seen stray animals in my neighborhoods, even with all the gnomes in play. However, I have been playing with a legacy family in the same neighborhood for three generations now and I started seeing strays all over. Not saying this is required, but it seems that the more ppl get old and die, the more pets will be left without homes. Also, while I haven't had a single stray come to my lot, my Sims do live next to a dog park, and today I saw TWO stray dogs playing there. I'm building relationships with them now. I haven't tested this for cats, but perhaps if you place the dog and cat parks, since they have food and other essentials for those pets, the strays might tend to flock there. So far it has worked for dogs. If the theory holds, it would be a great place to meet stray animals.
