I have been around and owned horses all my life, I love them dearly.
I have been to race meetings small and the big ones, these magnificent horses are treated well, their stable lads/girls spend many many hours with them, they are exercised regularly, they get the best diets, turnout pastures along with big 5* stabling. Veterinarians on call 24/7 with the best treatment money can buy.
I am more concerned about those folks who buy a pony/horse with no knowledge and then kill them with kindness, overfed, not exercised enough, ill fitting saddles, bits and bridles, I could go on but hopefully you get the picture.
Then there are the rabbits kept in small solitary cages above ground, when in nature they live in underground burrows with others.
House cats, never allowed to roam, dogs dressed up and carried around in handbags, along with my bete noir birds kept in cages, u able to fly.
