Yes the Sabretooth, having only one egg allotted in the Great Spinning Dino Egg Drum is amongst the rarest of the dinos! An amazing catch thru Random Egg. The next of the rare groups all have 6 eggs and are therefore six times more likely than your Tiger.

Since the TotalEggCount is now 2089, your chances after drawing a single random egg to get the Big Cat are exactly one in 2089. You can increase your chances if you like cats, by using the hurry catch method, The big cat has a hurry hatch of only 10.

Just replace your 2094 with the exact count of 2089.
