What kind of animal procedures are considered invasive and closely monitored?

Invasive animal procedures that are closely monitored typically include surgeries and experimental drug testing. These types of procedures directly manipulate the animal's body or involve significant interventions that can affect their health and well-being. Due to the potential for pain, distress, and lasting impact on the animals, such procedures fall under stringent regulations and ethical oversight.

The reason for this strict monitoring is to ensure that the welfare of the animals is prioritized and that any potential suffering is minimized. Animal welfare guidelines require that invasive procedures must have a valid scientific purpose and be designed to provide valuable scientific data while also ensuring the possibility of reducing distress as much as possible.

Basic care procedures, while important, are typically non-invasive and focus on the general health and maintenance of the animals, such as feeding, cleaning, and health checks. Exotic animal procedures could involve specialized care or research but do not necessarily imply invasive techniques. Observational studies involve observing animal behavior without direct interference and are generally considered non-invasive, thus not requiring the same level of monitoring.
