COW can count.

If you:
create a cat
create another cat
look
you will see 2 cats.

You can then:
create 4 cats
look
you will see 6 cats.

You can:
get one cat
get two cats
inv
You will see you are carrying 3 cats.

You can now:
drop three cats
look
There are now 6 cats again.

So long as the objects match exactly you will combine them into multi-objects. You can not create a blue cat and a red cat and expect them to show as 2 blue|red cats.

Cow understands these words:
a|an|another|one = 1
two = 2
three = 3
some = 20
many = 30
all|the = all of them

When manipulating objects with more than one (eg the 6 cats) you can refer to them as 'them' just as you would use 'it' eg:
create 6 cats
lock them
paint them as pink
pose them as playing

If you want to seperate multi-objects into their individual object just push one off:
create 3 frogs
push one frog
look
You will see 2 frogs and one frog

If you get then drop that one frog it will be re-combined into the others to become 3 frogs.

By default if you dont specify how many you will always be acting on all of the objects so the following ay the same:
get all of the frogs
get the frogs
get frog
