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.
Another name for the neuter surgery performed on male cats is castration. Male cats are usually neutered between 5 1/2 and 9 months of age, before habits such as spraying urine are started. Neutering involves the removal of the source of sex hormones and sperm cells, which is the testicles. The two incisions are usually so small that stitches or sutures are not even needed.
