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.
A. Male cats will be able to sire kittens when they are about 5 months of age. They should not be used for breeding, however, until they are 18 months of age. Female cats generally are sexually mature when they reach at least 80% of their adult weight. The timing of heat in a female cat is also dependent on the amount of daylight. Thus a female cat may have her first estrus anytime between 5 and 12 months of age. Feral (free-roaming) cats may reach sexual maturity earlier than indoor cats. Although a female cat is sexually mature when she is less than one year of age, she should not be bred until she is 18-24 months of age.
