this is possible. we got both our cats from a shelter. the one doing this was apparently born in a shelter. don’t know the details. in general he is perfectly fine. he seriously shows affection and trust towards us, but he is terribly simple to spook. each time the door rings, or a person visits, which he doesn’t know well, he is gone into the farthest corner, bit often comes back, when we ask him . the other one used to be a stray and apparently already moved quiet much. he had only one eye, and I’m pretty sure it had to do with him being the typical orange mad cat. first times we used a vacuum, he was charging to it and punching it.
