Another source of small animals is a well fed cat that brings
things home instead of eating them. About 1970, the cat of a
colleague in Cambridge collected 2 or 3 of the species used
in a study of mast cells in the brain. (The colleague put the
heads in jars of fixative - alcoholic Bouin or Carnoy - that
I provided.) This method of "sacrifice" was acceptable to the
referees when the work was eventually written up: A comparative
survey of the mast cells of the mammalian brain. Journal of
Anatomy 121, 303-311 (1976). The cat is acknowledged in a
footnote.
Another free kind of animal is any small fish that you can catch
with a little net. Slightly more expensive is a small goldfish from
a pet shop. Little fishes have easily recognized intestines and
livers, and are otherwise largely composed of muscle and associated
connective tissues, and the blood in their veins has nucleated
red cells. For the CNS of small fish (and small mammals too),
I recommend decalcifying the skull or vertebral column after
adequate fixation rather than trying to dissect out the brain
or spinal cord either before or after fixing.
