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.
Misty, Sheba and Twinkle were actually male kitties, too, and most of the time as soon as the owners found out the true sex of their pal, they changed it's name immediately! It can be difficult to determine the sex of cats, especially if there is no other kitten with which to compare the anatomy. In most litters there will be both male and female kittens and sex determination is easy. Take a look at the photos below and it will make determining the sex of a kitten much easier. Then choosing a name will be easier, too!
