How can I set a subdirectory as the root directory in .htaccess?

I want set a subfolder as the root folder, what means rewrite every requested URL by appending a directory before their root, like

example.com/cat/ -> example.com/public/cat/
example.com/cat/black/ -> example.com/public/cat/black/
example.com/public/cat/ -> example.com/public/public/cat/

I've tried

Options +FollowSymlinks
RewriteEngine on
RewriteBase /

RewriteRule (.*) /public/$1 [L]

But when I requested any of its page, I got Internal Server Error.

The rule is correct so far. The internal error comes from an endless rewrite loop.

When you request example.com/cat, it will be rewritten to example.com/public/cat. But this new URL is fed back into the rewrite module and again, example.com/public/cat is rewritten to example.com/public/public/cat, which is rewritten to example.com/public/public/public/cat, and so on, until some internal counter is exceeded and Apache reports an internal error.

To fix this, you must add a condition, which tells Apache to stop rewriting any further. For this, you can use one of the variables, which are set by Apache, when a rewrite occurs.

RewriteCond %{REDIRECT_STATUS} ^$
RewriteRule (.*) /public/$1 [L]

This checks, if REDIRECT_STATUS is empty (^$). When it is empty, do the rewrite. After the rewrite, REDIRECT_STATUS will be set and not empty, and as a consequence no further rewrites will be done.

If you wouldn't rewrite 

example.com/public/cat/ -> example.com/public/public/cat/

you could also check, if the requested URL doesn't start with public, e.g.

RewriteRule !^public/ /public%{REQUEST_URI} [L]
