People moves and 1/60 is way too slow.
Typically, you will need 1/(1.5x400) = 1/600 S to avoid lens shake but VR help a little.
Come on. How much will you spend to go to Africa? Don't want to buy a ticket to the zoo? You must practice how to shoot animals. most of the time, they will not look at you.
If I were you, I would go ISO 3200 to get my speed to at least 1/320 and use CH continuous clicking. So that you get that 1/1,000,000 chance an animal looks straight at you. I would be very pissed if all my pictures from Africa would look like these.
