I enjoy watching this series however after watching one today where Rusty the tiger is leaving the park I found totally upsetting and annoying how the keepers agree with this to remove him from his family the freedom of the park to have him locked in a cage for the rest of his life and how can you film it as if it is a happy event I agree the breeding programme is important but to move an animal like this it is as though you think they have no feelings I think there should be a better way to to do this.
