Relative Clause and relative pronouns for creatures?

Question

Relative Clause and relative pronouns for creatures (URGENT!)?
1.We know that "whose" is for possessive adjectives of persons.
2.What is the possessive adjective for things (non-living things and living things)?
3. Can anyone answer about the use of "whose" in the relative clause?

Please give examples for questions 1,2,3.

p.s. : I want to know more about the use of whose and the relative pronouns of non-living things and living things. Thanks

Answer 1

I always put "of which" for non-humans.

The cats, of which two were Siamese, filled the living room.
The examples I could give, of which these are only a couple, could fill this page.

Whose:
The man whose book I had borrowed demanded it back.

Answer 2

You can still use 'whose' for an animal or an inanimate object..eg:
The dog whose puppies were sold for £2000.
The book whose pages were ripped.

Answer 3

It depends on whether the non-human creatures are named or known. If you had 2 cats which had different coloured eating bowls. "My cats have different coloured bowls. Bill has a red bowl and my other cat, whose bowl is blue, is called Ben."

Answer 4

2. "its" for non-living things: "I am reading this book and ´its´ title is..." or maybe "which": I have a beautiful little stone ´which´ is very dear to me."

3. "I know of a person ´whose´ name is Jane."

Answer 5

I believe you would use "which" for things. Example: The window, which opens only from the inside, is locked.
