My Mac was poofed from people that let him out and never checked on him. Once, he was locked in someone's garage for 10 days while the owners were on vacation! The owners of the garage were out of town and didn't find him until they came home. They knew who he belonged to and took him home. Next day, he's out again. He was never fed by his owners and he wandered the neighborhood looking for food. He wasn't fixed and had never had shots. One of my supervisors at work took him back to his owner's house after she found him in her house...again! Mac knew which houses on the block had cats and cat food in them and he figured out how to get in each one of them (that is why I named him MacGyver, he's good at coming up with solutions to problems) Anyway, the upshot of this story is that the neighborhood felt so sorry for this kind, intelligent kitty that one of them poofed him and took him to work and gave him to me.
Yes, he did belong to someone else, and no, he wasn't technically abused, but he WAS NOT in a loving home! My supervisor later told me that they never even asked about him or looked for him. I not a big one for poofing, but sometimes it is in the best interests of the kitty!
