A tiger needs to think and consider its actions before it attacks. Tigers are smart hunters, so they need to consider all options and really think through a situation.
It's considering you for so long that it takes out a robe (りょ), a pipe, and an armchair and starts puffing away, staring intently at you. You didn't even know tigers could wear robes, but this one seems to use it to help itself think.
