Statement 1 is correct: Lions have no particular breeding season, and often synchronize breeding, especially after a pride takeover, raising the cubs communally. Statement 2 is correct: The bones of the cheetah's voice box form a fixed structure, with divided vocal cords that vibrate with both in and out breaths. This structure is the same for all the 'small' cats. While this design enables these cats to purr continuously, it limits the range of other sounds and prevents them from being able to roar. Cheetahs produce a variety of sounds including growls, purrs that generally denote contentment, chirps (between a mother and her cubs), and an "explosive yelp". Statement 3 is not correct: Leopards are territorial and mark their territory with faeces, urine and cheek- rubbing on trees. They can also leave scrape markings on the ground, trees or logs. This communicates to other leopards passing through that the territory they are in is occupied.
