This is the 5524th most frequent Chinese word.
兩隻
"兩隻" means "two (of something, usually animals or objects)."
The phrase '兩隻' is used to indicate two units of countable objects, usually animals, here referring to two kittens.
我有兩隻小貓。
I have two kittens.
In this sentence, '兩隻' specifies the number of dogs, again showing its use as a counter for animals.
他養了兩隻小狗。
He has raised two dogs.
Although '隻' is primarily used for animals, it can also act as a counter for objects of specific categories; here, it counts cups.
