        That one looks like it’s both. Not sure their eyes can turn that far to the sides, but the sockets seem to be positioned for both good focus ahead and a wide peripheral.

          My point is that they’re entirely forward facing. Calling it a mammal rule isn’t really accurate. It’s about whether or not the animal needs to judge distance to attack. Sharks use their vision to scan for prey above and below them, but they use their other sense to attack. Hawks and cats have a significantly different sense of vision, but both need to be able to accurately judge distance with their eyes when attacking.
