Billaj, I think you are asking whether we can use "Vos chats" to suggest that the cats belong to two or more owners. If this is what you meant, then the answer is no because in French, plural possesives such as "vos" are used to describe the thing and not the owner or speaker of that thing.
For example, it is correct to say "Ton chat" (Your cat) or "Vos chats" (Your cats) but "Vos chats" does not mean that the cats have two or more owners.
You can say "Nous avons un chat" (We have a cat), "Elles ont un chat" (They have a cat) or "Ils ont un chat" (They have a cat) to show that the cat has two or more owners.
ton chat = your male cat ; te chatte= your female cat; in some languages (french included) there is a more polite way of adressing the 2nd person when talking to older family members, to strangers.... "votre". "ton" and "te" are used with friends, colleagues, people of your own "rank". Hope that helpes
