Typical Mortars. Projected Grenades The most commonly used projected grenade is the 40 millime-ter (40mm) grenade. This grenade is also among the mostcommonly found UXO items. The 40mm grenade is about thesame size and shape as a chicken egg, as shown in Figure 7.
A female cat is called a queen. Male cats, on the other hand, are called toms. Cats are generally associated with the female of the species. When you call a woman ``catty'', for example, what you are implying is that she is very unpleasant and usually has a lot of nasty things to say about others.
Male cats do not go into heat. They are aroused when they smell the vaginal and urinal secretions that a female cat sprays when she is in heat. Once aroused they will actively seek the female. Male cats will fight over a female and the winner gets the chance to mate.
