I saw the image and it looked like a striped hyena.
It must of the one of the animal ambassadors that they go with their handlers to meet people.
Someone in the comments on Facebook said it was on exhibit in Lion Camp, and the wall visible in the photo is very clearly the wall in the lion exhibit. I'm not sure if that's a permanent thing or temporary thing, a rotation of some sort, or even a thing at all. I went two weeks ago and didn't see hyenas (I also didn't see lions) so I was wondering if maybe the reason I didn't see any animals out was due to some sort of transition.
