How long do the tours usually take? And will the animals come to us or will we come to them?

2 hrs, some animals will approach your car but you cannot leave your car during most of the tour

I don't think you can have pets in the car while you drive the park.

It really depends upon you and how fast you drive through the park. Animals will come up to the cars.

2 to 3 hours depending on how early you get there. You get there late. It might take you a long time to complete. Zebras and ostriches and some of the horned creatures were very social.
