Who gave Tigerstar his nine lives?

Erin hunter says that only cats in starclan can give lives so probably the cats who looked past his problems and focused on his sucesses such as helping silverstreams kits, becoming a strong warrior, ect

Mine: It is unkown who gave him his ninelives. However, I don't think he even had Nine lives. Seriously, "I don't think any StarClan cat would have the gut to. Except mabye Thistleclaw"

As I was saying; I don't think he had nine lives. Mabye that's why Scourge could kill him just like that. It is possible he may have lied that he had been accepted by StarClan like the leader before him: NightStar
