Thank you for your comments Mohammad, but this is the part I disagree with:
I can assure you that native English speakers use ‘he/his’ or ‘she/hers’ when the animal’s gender is known, regardless of the size of the animal.
They use it/its/ them/theirs when they don’t know the sex or they are discussing more than one animal.
It stems from early childhood as so many nursery rhymes and children’s tales give a gender to small animals. Here’s one: cef-colmon.org/mouse.htm
Dear teacher : thank you to find the answer.
When I asked this question I am totally confused that I have quite learned the pronouns since the primary school , I know it refer to the inamate things and not human senses , and it is full mistake to use she he for as pronoun for not human- kind , just till now I think the problem is solved , but let me add more ; they used the human characterstics to personify inanimate kind or animal through literary style and for example the poem of Robbert Hood when he used the pronoun ( he ) to personify his horse.
That’s right, Mohammad. Personification is a standard literary technique which is used a lot in poetry. Animals and inanimate objects (such as trains and windmills) are given human characteristics.
