I have a bear too, got it when made my account so the chance of getting it from my link is quite good I think
just try, and I hope you'll get one from my account
My friend got a panther, but not a bear so I dunno, you'll get a pet anyway!
just try to reach lvl 2 or 3
(you got 6 fights and if you win them all you reach lvl 3 in 5 mins!)
