As we haven’t gotten all the snags worked out of human rights yet, animals rights will keep evolving as well. There is absolutely murky area we get into when we debate things like why whales in Sea World is bad vs all animals in captivity is bad. But I’m glad people are having these debates.
For good or bad, the price is going to keep a lot of people away, so the birds aren’t subject to hundreds of people. It’s also probably a plus people can essentially rent an animal (with trainer included) instead of trying to get their own animal to see if they like it.
I have seen the primate paintings, and the aquarium in NJ I know did hippo nose print paintings, but I never thought too much about that. I know some people are very against animals being made to do anything though, and I can respect that opinion.
