The picture of the suspicious-looking zebra has gone viral on social media.
"We finished our tour then we made a decision to take some pictures".
Student Mahmoud Sarhan visited the attraction last week and accused the zoo of malpractice after noticing the "zebra" appeared smaller than normal with larger, pointier ears. Oh yes, and their stripes are not smudged - unlike the creatures in Cairo.

Whether California can argue that economy standards and emissions are tied will determine the overall outcome of the case. The issue is complicated by the fact that California is not alone in its pursuit of more stringent emissions standards.
Zoo visitor Mahmoud Sarhan spotted what he said was a donkey painted to look like a zebra at Cairo's International Garden public park.
Zoo officials denied making an ass of themselves, with the facility's director telling local radio station Nogoum FM that the animal is in fact a zebra and not a donkey in disguise. "I knew the shape of donkeys and also I knew the shape of zebras so it was easy to know".
"No reputable animal care facility would subject a skittish animal like a donkey to the stress of being restrained and sprayed with chemicals like paint, which could cause a painful allergic reaction, and PETA hopes that Cairo authorities are fully investigating this matter", PETA Foundation Vice President Delcianna Winders told CNN in a statement.
After noticing one of the "zebras" in the pen had an unusual black smudge on its face he posted a photo of himself with the animal on Facebook. Three years later, another Gaza zoo put up stuffed animals on display. And in 2013, a Chinese zoo had a mastiff dog labelled as a Tibetan lion.
