MoP Beta: Achievement Adjustments

Many pet-related achievements were updated in the latest beta patch, and one of the achievements rewards a new pet! [source]

• Changes were made to quite a few pet-related achievements. The points that are rewarded for them have been reduced by half for many of these achievements. [source]
• The Going to Need More Leashes achievement has been changed, and now only requires the collection of 250 unique pets (down from 300).
• Previously, the Feral Vermling was the reward for completing the achievement Zen Pet Hunter (Capture 200 pets in a pet battle). It has been moved and is now the reward for Going to Need More Leashes (Collect 250 unique pets).
• That's a Lot of Pet Food (Collect 400 unique pets) rewards a new companion, Venus!

What type of pet could Venus be? We're going to have to wait for a hint, but here's hoping that it's out of this world!
