Consider the following statements: 1. Lions do not have a particular breeding season. 2. Unlike most other big cats, cheetahs do not roar. 3. Unlike male lions, male leopards do not proclaim their territory by scent marking. Which of the statements given above are correct?

Statements 1 and 2 are correct, but statement 3 is incorrect. Lions are polyestrous breeders and can mate at any time of the year; they do not have a fixed breeding season. Cheetahs cannot roar because they lack the specialized larynx structure (the divided hyoid bone) that other big cats possess; instead they chirp, purr, and growl. Male leopards, like male lions, do mark their territory using scent through urine spraying and scratch marks, so statement 3 is wrong.
