Thats a good point. But I still think that what we already know would sugest otherwise... Animals that stalk are most offten camoflaged and seem to hang next to a surface so its hard to pick 'em out from the back ground. And eventhough we have know idea what colour/s Meeches are they still look like they would stick out like a sore thumb... espesally if their is a pack of 'em hanging around.
A better hunting method for the Meeche would be Ambush. How fast they are would depend on the size of their packs. They have to be faster with 3 or less but would still probly be faster with up to 5 or so due to the pray having a home feild advantage.
