Adoption Issues

I am the director of a 501c3 animal rescue. We have an adopter that is failing to comply with our spay/neuter agreement within our adoption contract that was signed at the time of adoption. They have been avoiding all methods of contact for over 60 days. I’m hoping to find out what the best avenue to hopefully gain compliance would be? While our contract states failure to comply is grounds for removal of the animal from their home, we’d really prefer not to go to that extreme.

My ex and I split, and she and I had an agreement for sharing custody of my dog I acquired. Now she is trying to stop me from having my dog at all.

I have surrendered my cat to a no-kill shelter because I had to move out of the state and because I was having some health problems at the time and I couldn't take care of it. Since I haven't moved yet and I am still in Las Vegas, NV, I have asked to see my cat because my son and I, we miss him. The shelter told me that he has been adopted within the same month when I surrendered, and that they can't give me information of the adopter person for privacy purpose. I have not asked for the Adopter's address or anything related, I've asked if they can call the person who adopted my pet to let me see the pet one more time or send me a picture of him because I miss him that bad. They are not even returning my calls or emails back. I feel they have no right to treat people's feelings like that. What can I do?

My cousin is requesting me to adopt a cat for her and she will keep him. She cannot get him because she lives in an apartment and they are requesting an actual house. I am allergic to cats and although I love them, I do not want the legal responsibilities if she decides she no longer wants him. Is this okay or should I just let it be?
