Most of the damage was done in the first half as the rampant Wolves ran through the feeble Tigers defence for seven tries.
Four more followed after the break as the Wolves moved level with neighbours Widnes, who they face in an intriguing derby next week, at the summit.
The tries were shared out but the inspirational Chris Sandow, Tom Lineham and Ben Currie all finished with two apiece.
The procession started after just five minutes as Sandow wrong-footed the defence with a clever grubber kick and followed up to touch down. A second quickly followed as Kevin Penny went over on the left and Lineham dived over for another on the opposite side.
There was conjecture over who claimed the fourth after a powerful charge by Ashton Sims pushed the Tigers defence back. Kurt Gidley was initially credited with the score but Matty Russell and Brad Dwyer also emerged from a pile-up.
There was no debate over who got the next as Russell forced his way through some poor tackling to set-up Ryan Atkins.
Worse followed for the Tigers as Sandow broke from the resulting restart to spark a brilliant counter-attack that Currie finished off.
Sandow jinked through before Cas finally stirred to set up former Warrington star Joel Monaghan’s first try in Tigers colours. Gadwin Springer sped through a gap to further reduce the arrears but normal service was resumed soon after the hour as Dwyer twisted his way out of a tackle and crashed over. Lineham brilliantly claimed a high kick in the corner to grab his second before Currie raced over for his second.
