Is it possible to find out who adopted a certain cat from a certain shelter? If that is at all possible I’d very much appreciate your ideas or advice. Thank you!

It\\\’s highly unlikely that they would give out the private contact information of someone who has adopted one of their cats.

I would call the shelter and ask them what their policy is - although I suspect they would say no. On the other hand, if you could positively identify the cat as previously yours, they may be willing to call the person/people who adopted it.
