From the artist:

Why is it legal for kids to buy sentient beings? ⁣
⁣
This comic is for all the hamsters that I caused suffering to when I was a child. They are SO CHEAP, less than 1USD at that time. I wore my primary school uniform. The pet shops just let me take those poor hamsters home by hand….⁣
⁣
I was so clueless to what I was doing, I put two hamsters together and one day there was 8 pink babies.⁣
⁣
I accidentally starved one hamster (I just forgot!), and I “live and let live” and “set them free” to the little park downstairs. ⁣
⁣
I feel terribly sorry for all my hamsters.⁣
