Sounds like a pretty tough case as far as getting compensation for your cat. Yes, you have a chance. I would contact an animal attorney to represent you.
If you have proof that the person vandalized your house, other than just a suspicion, you can bring a claim for damages against the person and get an anti-harassment order.
A criminal lawyer may have a good handle on how to show harassment by the officer.
This is not to be construed as legal advice. I do not have an attorney client relationship with you.
If you don't already have a lawyer, hire one to help you. The law is complex and there may be things that can be done that you didn't know about. Good luck!

While I agree with my colleagues that you should speak with a local attorney I want to point out that there is an easy fix - keep your cats inside.
If we do not have a signed fee agreement I am not your attorney and this is not legal advice.
