I think the time of the circus being all about animals is over .
There were far more ....'human'' tricks then animal tricks. I remember when I was young and going to the circus every couple of months ( 20 years ago .. maybe a bit more.. ) there were very few human tricks.. and they were done quickly, between the animal shows so that you could watch something while they cleared the stage for the next group of animals.
I remember Camels, Lions, Tigers, Panthers.. Bears.. you name it. It was like a traveling zoo.
now, this time.. we saw elephants .. about 8 of them.
Horses. Arabians, Shetlands, some painted mares and a couple of foals.
6 Tigers, one Pig, 2 goats.. and a bunch of Poodle dogs.
Granted, watching it was fun but it seemed.. less animal focused then when I was younger, or I was just more fascinated with it then.
I do remember hearing terror stories of animals being chained up for days on end while they were being 'trained' .. no real roaming allowed and many were left to live in their cages with little thought to getting them out.
My first reaction to that was not a humanitarian one.. it was more along the lines of.. How stupid can one be to lock up a Tiger like that, then expect them to be sedated and not attack you when they are let out?
That would be like locking your kitty cat in the bathroom for awhole day and then wondering why he is so excited and jumping around you when you let him out.. Its just that a Tiger will kill you if he gets that excited.
