Disgusting insect cage fights on the Internet. Insects are animals too!

On the Internet I've seen many disturbing videos with cage fights between insects, lizards, bullfrogs and other creatures being deliberately put to fight among themselves. Because the insects are not considered sentient animals, this should not give the right to some to deliberately put them in life and death situations, forcing them to fight in the cage. Insects and other species that are not pets, living on this planet long before us, shouldn't be a joke or an unauthorized experiment for sadistic pleasure and for fans. I remember David Attenborough looking in awe at a worm that is of the oldest species that lives on dry land, and I wonder: Who are we to be doing such things? Animal rights should be the rights of all animal species. No bug, no lizard should be our sadistic joke.
