Question

what happened to the all'animals in tha end​

Answer 1

Answer:

That depends on the experiment. For studies with rodents, the animals usually need to be euthanised at the end of the experiment, in order, for instance, to examine their organs. Whenever possible, larger animals, such as dogs, will be used in multiple experiments as long as these do not cause an excessive level of distress and the animals are able to recover completely between experiments. Furthermore, dogs are often adopted by private owners once they are no longer needed for experimentation. Wild animals are normally released back into their natural habitat, if they had to be captured.
