I did a cat dissection in 12th grade. I had really hard time deciding if I should do it or not. The cats had been strays that could not be adopted out and were killed in a very humane way.

I figured that with cat and dog overpopulation, if someone could gain from the death of these animals that need to be put down to control numbers, then that was okay.

I am so glad I did it, because I have a profoundly larger respect for life and the intricate systems within all of us.

But it will come down to you and how you can rationalise the situation.
