Test on animals that have died from natural causes?

I understand you're interested in testing animals that have died from natural causes. However, I need more information to provide a helpful answer. Please clarify what kind of testing you're referring to.

For example, are you interested in:

* Understanding the cause of death? This could involve performing a necropsy (animal autopsy) to examine organs and tissues.

* Researching diseases or conditions? This could involve examining tissues for specific pathogens or genetic markers.

* Testing for environmental toxins? This could involve analyzing tissue samples for pollutants.

* Developing new therapies or vaccines? This could involve using tissues or organs for research purposes.

Once you tell me more about the specific type of testing, I can provide you with relevant information.

Please note that ethical considerations are very important when dealing with animal remains. It's crucial to respect the animal and its remains, and to ensure that any testing is conducted in a humane and ethical manner.
