is it true that female tigers only have four teeters?

All felines including tigers have eight teats (link 1). In fact, all felines are very, very similar biologically speaking... they are all thought to have evolved from a common ancestor a mere 10 million years ago.

There were times in history when cat milk was highly prized. That of tigers, I'm told, has a more 'robust flavour' than most other cat milks. Just in case you were wondering.
