When you select your male you want to be very sure

Prepare a concentrated stock solution by adding 10 gm
Benzocaine to 100 ml ethanol. For euthanasia add 15 ml of the stock solution to one
liter water. After at least 10 minutes submerged in the solution, the male is ready
for the surgery. Check for depth of anesthesia by a loss of righting response and
loss of response to painful stimuli. Wearing gloves, remove him and place him
belly up on a paper towel. Using forceps, grab the skin and snip with a
pair of scissors. Once you have nicked the skin, make a shallow incision up the length of his
body. Fold away the skin and repeat this with his muscle layer.

Repeat this with the other side of the body.
Wrap the body and place in the freezer until you can
properly dispose of it.
