11:13-21. On the back of the scroll, a name of G-d is written. The scroll is then rolled up and placed in the case, so that the first letter of the Name (the letter Shin) is visible (or, more commonly, the letter Shin is written on the outside of the case). The scroll must be handwritten in a special style of writing and must be placed in the case to fulfill the mitzvah.
In addition, leopards also make various other sounds, for example, growls. The subspecies of puma (also called cougar or mountain lion) found in Florida is often called the Florida panther. This is a completely different animal.
As far as making noise voluntarily goes, it is quite common for a turtle to do so during battle, courtship, mating and egg-laying. Most turtle noises are hisses; however turtles have also been known to make noises that include grunting, hooting and clucking. What is even more interesting as far as sound goes is that turtles do not have outer ears. They have inner ear structures but do not necessarily respond to noise.
