I watch all the zoo shows. I think it's awful how the keepers of The Secret Life Of The Zoo sit back and watch illnesses grow. They could take blood or do a test. Too often they sit back so long the results are not good. Their reaction time has a lot to be desired. Too many animals which could have been saved died.
Maybe they need to watch Crikey It's the Irwins. Their response time is immediate and their love of the animals they care for is evident!
