problems with passive [frenzy] bm spec

hi all

i have a problem..some days ago i noticed that my pets didn't get more buff from passive (spec bm) "frenzy".i don't understand what's happened.i asked to other hunters but they don't have this problem
so i tried to cancel cache,reset talent/specialization,tame new pets but nothing. frenzy don't stack,it's always inactive. how i can resolve this? sorry for my bad english

Your pet is a cat? I dont know if it aplies to SBs but seems luke frenzy is buged for cats, theres a report on bugtracker but not confirmed yet.

yes but also i tried with raprtors,devilsaur,wolfs...nothing...still don't work
