Yes, these acts are truly horrible. My mother does a lot of research into these topics and so I know a fair bit about what goes on in these areas, plus I've seen some horrible things myself in person.
Cosmetic testing is sickening, complete torture. Animals such as rabbits, kittens, mice and so on are force fed through a tube, most up to the point where they're choking. They have creams and other products put in their eyes and all over their skin which obviously stings and irritates horribly. I saw an image of a kitten with a bolt drilled or pushed through it's mouth to keep it open so it could be fed, I felt like crying ;_;
Where I used to live cock fighting was a popular "sport", it wasn't illegal at all and many of the locals were into it including the kids. Roosters have their crown (the red spiky thing on top of their head) cut off so it won't bleed and get in their eyes when they're fighting. They also have their spur (a claw at the back of their foot) cut off to fit the gloves with the razors on. Not all people use these gloves though but just let the roosters fight with their own claws. They usually hold the two in front of each other or "throw one" at the other.
My pet rooster, Disco, was such a lovely and friendly bird. He always wanted to be next to you and he would do a little "dance" when you click your fingers, he loved attention and liked sitting on your lap. We found him with his crown half cut off and blood all over his face. Later on he was stolen along with the neighbour's chickens as well, we have a fair idea what was to happen to him.
Horse racing, personally I've never been a fan of it from the start. The races that use the jumps and hurdles result in broken necks and leg injuries, and of course these injuries cannot be fixed and the horse is put down sadly. Not sure how many years ago I saw some horse racing footage, the horse flipped over and broke it's neck as well as colliding with another horse. Both the jockeys were okay in the end of course, same can't be said for the horses. The "whip" the jockeys use are often misused and 64% of the non-padded part actually ends up hitting the horse. After foals are taken away from their mothers they are to trained as soon as possible. Considering their skeletal system is still immature it causes the risk of injury, they are not ready for hard training. Any horse that is not suitable to the racing industry is sent to the slaughter house, same goes for horses that are no longer fit for racing and of no use to the money making scheme.
As for zoos, some do not have confined spaces while others do. I've been to a lot of different zoos, one had a large paddock for zebra and rhinos with some enclosures that were a bit smaller than the average house. One zoo though had concrete "rooms" for some of the animals. This was in a tropical climate and two tigers were in this concrete room with empty water bowls while some of the other tigers had an enclosure with grass, trees and a small pond. No this wasn't one of the indoor rooms they keep them in for surveillance stuff it was a concrete room with no roof and bars, it was outside for visitors to walk past and observe.
I understand the part about how the animals are taken from their natural habitat but that can be considered a good thing. Many of the animals in captivity are endangered and are killed in their natural habitat. There are more tigers living in captivity than in the wild. Habitat loss, poaching, hunting and loss of food would be something these animals would have to experience in the wild. While they are lucky to be avoiding these issues some have to live in the cramped and horrible conditions you mention, not all zoos are like that but there are many that are.
Also I want to bring up the point about water parks that keep dolphins in swimming pools such as in water parks and zoos. As cool as it would be to see dolphins doing tricks and maybe swimming with them in the same pool it is harming them. Dolphins do not naturally live in chlorinated water, it can cause their skin to peel, hurt their eyes as well as make them sick. They use echolocation to navigate but living in tanks cause their sonar waves to bounce off walls which can make them insane. Dolphins in the wild can live up to 90 years old but in captivity their lifespan is shortened and live just over 10 years. Being forced to perform tricks for food day after day is just cruel. During dolphin catching many drown in exhaustion trying to escape nets. There is also the issue of loss of family connections after being captured from the wild. By taking one dolphin from the pod it will disrupt the whole group. Any that escape capture will be become frantic if they see one of their companions captured and will even try to save them.
Ehh, long post, I'm so tired x_x
Thank you for sharing Thyme, I personally think more people need to know more about the cruelty that goes on.
